or "failed to set priority for %d (%s)"?

Subject: [PATCH] renice: improve messages specifying what ID is referring to

This version makes more clear the printed message specially when the
--user option is used.

Old version:
   $ renice 19 10 -u fra -g 1
renice: 10: setpriority: Operation not permitted
renice: 1000: setpriority: Operation not permitted
renice: 1: setpriority: Operation not permitted

   $ renice 19 -u fra
1000: old priority 0, new priority 19

New version:
   $ renice 19 10 -u fra -g 1
renice: failed to set priority for 10 (process ID): Operation not permitted
renice: failed to set priority for 1000 (user ID): Operation not permitted
renice: failed to set priority for 1 (process group ID): Operation not permitted

   $ renice 19 -u fra
1000 (user ID) old priority 0, new priority 19
