Subject: util_run_program: *really* restore signal mask before executing event RUN commands

util_run_program: *really* restore signal mask before executing event RUN commands

The previous patch was almost, but not quite, correct.  Rather than
restoring the signal mask it actually tried to make an even more
restrictive signal mask (had SIGALRM been blocked when udevd started,
anyway).

Fix it harder.
