signal: Restore errno on exit from signal handler.

This probably is not necessary since generic_signal_handler() calls
exit(3) if the write to the signal pipe fails. However, nobody is
going to stop write(2) from setting errno also on success, so let's
play safe and always restore its value on exit.
