Also formally allow dumpstate access to all services and grant system_server
access to address the following non-system_server_service entries:
avc: granted { find } for service=drm.drmManager scontext=u:r:system_server:s0 tcontext=u:object_r:drmserver_service:s0 tclass=service_manager
avc: granted { find } for service=nfc scontext=u:r:system_server:s0 tcontext=u:object_r:nfc_service:s0 tclass=service_manager
