FreeBSD bug 204157: If filesystem does not support birthtime, then ma…

…ke all birthtime comparisons succeed.

This is a bit of a hack:  We should also have tests that verify
different birthtimes.  When/if that happens, we'll need to add
a real system probe to determine whether birthtime is actually
supported on this particular filesystem and skip tests accordingly.
