The s390x don't use hwclock and there is no plan on using it (ever).

The s390x uses `ccw` devices and not `pci` ones and this device has
different properties than checked in the original test.

The Avocado's process.system_output does not uses `shell` while this
test uses shell capabilities (ls ...; true), which fails. Let's always
enable `shell=True` in this test.

The s390x is not suppose to use pci devices, but channel devices
instead.

base image option: only sectors above this image are streamed.(optional)
So if there is only one snapshot, base->sn1, the stream will start from sn1
to sn1, that means no data streamed, so it will complete immediately and
still have base as it backing file, which cause backing file check failed

Fix:
1. By default set base option to None. Currently only case
block_stream.backingfile_option need to set this option
2. Set base to guest image_file only when call set_backingfile() function
3. If base is none, then check_backingfile_exist() should not be called,
it will report error
