Slave - remove list of supported services

- remove list of supported services from "perun" script supported
	services are determined by existence of process-$SERVICE_NAME.sh
	script

- bugfix of b2f0a8607cec22421de34cc81762785c2ee5e5ff - there was missing
	entry in supported services in "perun" slave script. There is no more
	supported services, so this issue is fixed now.
