tests: disable test-nointerrupt on Windows

Per the followup discussion[1].  proc.send_signal(INT) in timeout.py raises a
ValueError because of an unsupported signal.  I don't like missing test coverage
for this on Windows.  But this is the last test failing on Windows, and red all
the time hides new failures.
