llmnrd: exit gracefully on select() EINTR
If a signal was caught, select returns with errno set to EINTR. The signal handler already set llmnrd_running = false. This will also make sure the log message moved by commit a1a821814101 ("llmnrd: only async signal safe functions may be called in signal handler") will get logged correctly in all cases and the process will exit gracefully.
