[PATCH] t0005: skip signal death exit code test on Windows

From: Johannes Sixt <redacted>

The test case depends on that test-sigchain can commit suicide by a call
to raise(SIGTERM) in a way that run-command.c::wait_or_whine() can detect
as death through a signal. There are no POSIX signals on Windows, and a
sufficiently close emulation is not available in the Microsoft C runtime
(and probably not even possible).

The particular deficiency is that when a signal is raise()d whose SIG_DFL
action will cause process death (SIGTERM in this case), the
implementation of raise() just calls exit(3).

We could check for exit code 3 in addition to 143, but that would miss
the point of the test entirely. Hence, just skip it on Windows.
