update openrc gentoo based outdated script in sync with current gentoo

* This script its from ancient webmin era.. we need up to date to
  be able to use for alpine and modern gentoo linux distributions,
  gentoo still uses Openrc for many things no matter if you choose
  other init systems
* Fix status command not available to, by the detection of the pid,
  this is using the config pid variable from webmin config miniserv
  is need for future support on issue #2353 and related to #835 that
  just assume init sysv systems or the other s*** only.
  Still is pending future support for openrc init system but with
  this path next changes are more easy to do
