Note that since systemctl shows puppetmaster.service as a unit file the
init script wont' be used at all so you can ignore the file in /etc/init.d
... that's just there because puppetlabs are being lazy and using the same
RPM on EL6 as EL7 rather than having the right files for the right
subsystems on the right distribution versions ... ./sigh
Otherwise you're down to standard troubleshooting process - use ss -tlnp to
identify the process that is holding the port open, systemctl cat
puppetmaster.service and see what it's trying to do etc etc
