dev-util/buildbot-worker: Make the init script multi-instance capable
Use the same method as the buildbot master init script for multiple instances on the same host. Add RUNTIME_PYTHON variable (optional) to the conf.d to specify the desired python to run it from. Package-Manager: Portage-2.3.6_p65, Repoman-2.3.2_p133
