On 03d81fea, we let the Avocado developer choose the Python version
to use by setting a PYTHON variable that gets passed to `make`
commands.

But, we missed the case when the execution of the selftests is not
done in parallel.

Given that the setUp() phase is not useful for test_disk_space, and the
custom cleanup done in the test is better had at the tearDown() phase.

Additionally, the following changes where made to make it more reliable:

 * Avoid the busy loop giving modprobe some time between attempts
 * Use "modprobe -r" instead of rmmod, which handlers module dependencies
 * Do an explicit check for status
 * If "modprobe -r" doesn't succeed, it's not a test failure, but a test
   a test error (given that the get_diskspace() function already ran
   and succeeded).

Ideally, the module removal would be done by the linux_modules.unload_module()
but there are some issues with that function that needs addressing first
(such as returning a meaningful result).

The logic of _make_test_runner() is too simple, and can be further
simplified, to justify a separate method.  Referring back to the
implementation of _make_test_runner() makes reading the code harder
IMO, so let's inline it.

The related command line option is "--keep-tmp", and it keeps the
setting on "keep_tmp", so it just makes sense, for easier reading of
the code, to name the variable in a similar way.

While at it, let's prevent crash if "os.path.exists()" in "cleanup()"
is given a tmpdir that is None.  This was not caught before because
the default value of "__remove_tmp" would prevent "os.path.exists()"
to be reached.

A gzip file doesn't have all the "archive" properties that a tarfile
or zipfile has, but still, it could be useful to wrap in the archive
module.

At this point, support is being added to allow for files compressed
with gzip, to be acknowledged as valid in avocado.utils.is_archive()
and transparently handled with avocado.util.uncompress().

The goal of this implementation is to allow for gzip files, which
are compressed tarbals, to be properly handled at uncompress() time.

The PYTHON variable evaluation changed recently resulting in different
than default PYTHON variable in some plugins resulting "make link" in
setting Avocado under different python than the linked plugin (eg.
Avocado-vt). Let's make sure we use the same python by passing
PYTHON="$(PYTHON)".

The newly released pylint version 2.2.0, changed its default behavior
(enabled) the following checks:

 * :unnecessary-pass (W0107): *Unnecessary pass statement*
   Used when a "pass" statement that can be avoided is encountered.

 * :unused-import (W0611): *Unused %s*
   Used when an imported module or variable is not used.

Let's apply fixes to those checks, and at the same time, pin the
pylint versions so that our CI environment is more stable (code that
test our code -- pylint -- doesn't change, while our code changes).

For Python 2, the latest release was 1.9.3, so let's use that.

The current utils kernel module has no tests. Recently it was added a
fix[1] to the process of kernel url building. To keep this process
without future regressions, this change adds a proper test for it.

It's important to note that a new internal method was added to the
KernelBuild class to make easier to test it. Indirectly it's an
improvement of download method that now is shorter and more explicit.
