Subject: pidofproc: use "pidof -c" to avoid pidofproc results from containers
 or chroots

From pidof's manpage:
  -c     Only return process PIDs that are running with the same root
         directory.  This option is ignored for non-root users, as they will
         be unable to check the current root directory of processes they do
         not own.

Closes: #888743
