Description of problem:
When starting an initscript directly (without systemctl) and if it checks the pid with pidofproc, the output of pidofproc is always true as pidof in /etc/init.d/functions is called with -m that does not exist anymore, and thus the initial script is not omitted.

Version-Release number of selected component (if applicable):
RHEL 8 
procps-ng-3.3.15-1.el8.x86_64
initscripts-10.00.4-1.el8.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Use an init scrips with pidofproc $progname
2. the output will always be true if the service is run through /etc/init.d/service start
3.

Actual results:
the service does not start if not called with systemctl

Expected results:
the service should start with /etc/init.d/service start

Additional info:
A workaround is to run "sh /etc/init.d/service start" as the script will be omitted by pidof.
