add /var/lock/bts_rf_lock and /var/run/osmo-bts.pid for rf control 

an external application can create /var/lock/bts_rf_lock and then kill
the pid in /var/run/osmo-bts.pid in order to shut down the BTS.  Any
re-spawning scripts will trigger, but osmo-bts will refuse to start up
until /var/lock/bts_rf_lock is removed again.
