[PATCH 03/10] t/sigfd: better checks related to SIGWINCH

[Eric Wong]

Check to ensure there's a numeric value of SIGWINCH defined for
the given platform.  SIGWINCH may also fire while the test is
running due to a user resizing their terminal, so a boolean test
to ensure it fired rather than an exact value check is more
correct.
