Xin LI 981dfb0965 - Fail when the utility is not invoked as rtprio nor idprio.
- use warnx() to tell the user whether a process is running in normal,
   idle or realtime priority. with the old code it would have been possible
   for another process to send data to stdout between
	printf("%s: ", p);
   and
	printf("* priority\n");
   and thus break the formatting.
 - 'rtprio 10 -0' triggeres non-intuitive behavior.  It would first set the
   priority of itself to 10 *and* would then try to execute '-0'. Of course,
   setting the priority of [id|rt]prio itself doesn't make a lot of sense,
   but it is intuitive compared to the previous behavior.
 - 'rtprio -t --1' will actually pass over the '-1' to rtprio().  Now
   invoking rtprio like this will catch the wrong usage before passing
   over the invalid argument to rtprio().
 - Garrett Cooper suggested to add further diagnostics where the failure
   occures, if execvp fails.
