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.

"""Tool read primitive events from a pipe to produce a catapult trace. For now the event stream supports START $SESSIONID ... and END $SESSIONID ... events. Everything after the SESSIONID (which must not contain spaces) is used as a label for the event. Events are timestamped as of when they arrive in this process and are then used to produce catapult traces that can be loaded in Chrome's about:tracing utility. It's important that the event stream *into* this process stay simple, because we have to emit it from the shell scripts produced by run-tests.py. Typically you'll want to place the path to the named pipe in the HGCATAPULTSERVERPIPE environment variable, which both run-tests and hg understand.
