mac802154: Handle received BEACON_REQ
When performing an active scan, devices emit BEACON_REQ which
must be answered by other PANs receiving the request, unless they are
already passively sending beacons.
Answering a beacon request becomes a duty when the user tells us to send
beacons and the request provides an interval of 15.
