Issue #3864: Skip three test_signal tests on freebsd6 due to platform bug.

Browse source 
Two itimer tests and an interprocess signal test fail on FreeBSD 6 if
any test that starts a thread runs before test_signal.  Since FreeBSD7
does not show this behavior, the bug is most likely a platform bug,
so this patch just skips the failing tests on freebsd6.
