[Qemu-trivial] [PATCH for-2.10 4/4] bsd-user/main.c: Fix unused variable warning

[Peter Maydell <peter.maydell@linaro.org>]

On OpenBSD the compiler warns:
bsd-user/main.c:622:21: warning: variable 'sig' set but not used [-Wunused-but-set-variable]

This is because a lot of the signal delivery code is #if-0'd
out as unused. Reshuffle #ifdefs a bit to silence the warning.
