[PULL 03/10] tests/functional/test_vnc: Do not use a hard-coded VNC port

[Thomas Huth <thuth@redhat.com>]

Two tests here are using the hard-coded VNC port :0 ... if there
is already a QEMU or other program running that is using this
port, the tests will be failing. Fortunately, QEMU can also
auto-detect a free port with the "to=..." parameter, so let's
use that for the tests to avoid the problem.
