Allow AID_RADIO to restart the ril-daemon.

Browse source 
This enhances robustness by allowing the Telephony Framework to restart
ril-daemon if it notices some catastrophic failure.

Added setprop ctl.restart.
Added ril-daemon to setprop control_perms and allow users/groups
with the AID_RADIO ID to control it.
