udevd: use signal_to_string() instead of strsignal() at one place

strsignal() sucks, as it tries to generate human readable strings from
something that isn't really human readable by concept. Let's use
signal_to_string() instead, making this more grokkable. Difference is:
SIGINT gets translated → "SIGINT" rather than → "Interrupted".
