signal: Replace force_sigsegv(SIGSEGV) with force_fatal_sig(SIGSEGV)

signal: Replace force_sigsegv(SIGSEGV) with force_fatal_sig(SIGSEGV)

commit 6f085a3987892099ba1edf2cd321e10b87365168 upstream.

Now that force_fatal_sig exists it is unnecessary and a bit confusing
to use force_sigsegv in cases where the simpler force_fatal_sig is
wanted.  So change every instance we can to make the code clearer.
