Detect and suppress an additional gmtime() warning in test_util.c

Fixes bug 29922; bugfix on 0.2.9.3-alpha when we tried to capture
all these warnings.  No need to backport any farther than 0.3.5,
though -- these warnings don't cause test failures before then.

This one was tricky to find because apparently it only happened on
_some_ windows builds.
