The fixed path and ports get in the way of running our tests and
builds in parallel. Instead of using TESTPATH we use mkdtemp() and
instead of a fixed port we allow the kernel to assign one and query it
afterwards.

Ideally test directory creation should be common functionally across
all TCG tests but this could complicate an already huge patch series
so we mark it as a TODO for next time.

Un-comment the remaining tests.

I removed the itimer value tests because I'm fairly sure a re-arming
timer will always have a different value in it when you grab it.

I've also fixed up the clone thread flags as QEMU will only allow a
clone to use flags which match glibc. However the test is still racey
so it remains disabled by default - it can be run by passing any
additional parameters on the command line.
