  rhel: Use PIDFile on forking systemd service files

Currently, PIDFile is not used in systemd service files with
Type=forking. This means sometimes systemd fails to restart a daemon
that is killed (with SIGKILL) or that is crashed.

This commit adds PIDFile to all systemd service file with Type=forking
in order to always have the correct PID to monitor.
