tests: conditionalize missing output in test-racy-mutations.t on Windows

No idea why this is only missing on Windows.  I verified that the line marked
as missing directly above this for the changelog is, in fact, missing on both
Windows and Linux.  So there's probably work to do in this area on all
platforms.  It would be nice to figure out what is going on, but this appeases
CI in the meantime.

#require no-windows no-rhg

XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

Kludge to emulate timeout(1) which is not generally available.
