fix RH kickstart realted issue with service state

When calling highstate from a RedHat kickstart environment and attempting to apply service state an out of index excpetion would get thrown.  This is due to the runlevel command returning 'unknown' instead of an actual runlevel.  Updated rh_service module to assume that 'unknown' can be treated as runlevel 3.  Also you may or may not have /sbin in the path during a post kickstart script run, so all commands in the service module were updated to prepend /sbin to the command.
