ServiceUtilities: don't do RECORD_AUDIO check for system server
Only one system server seems to exist across multiple-users; however,
when the primary user is backgrounded, system server loses its
RECORD_AUDIO permission. Through a number of steps this prevents the
secondary user from starting any services that use the SoundTrigger HAL;
specifically, this was found because it prevents Oslo from functioning
when a secondary user is active.
Bug: 139839188
Test: Oslo use cases pass
