ServiceManager: Allow system services running as secondary users to add services 

This should be reverted when all system services have been cleaned up to not
do this. A process looking up a service while running in the background will
see the service registered by the active user (assuming the service is
registered on every user switch), not the service registered by the user that
the process itself belongs to.
