While running in parallel, the VNC tests that use a TCP port easily
collide. There's a number of possibilities to reduce the probability
of collisions, but none that completely prevents it from happening.
So, to avoid those collisions, and given that the scope of the tests
are really not related to nature of the socket type, let's switch to
UNIX domain sockets created in temporary directories.
Note: the amount of boiler plate code is far from the ideal, but it's
related to the fact that a test "workdir"[1] attribute can not be used
here, because of the 108 bytes limitation of the UNIX socket path (see
ad9579aaa16). There's a fair assumption here that the temporary
directory returned by Python's tempfile.mkdtemp() won't be anywhere
close to 100 bytes.
