fascinatemtd: remove deprecated and (likely) unneeded RIL properties

- ro.radio.noril is deprecated. no longer exists in telephony framework
- ro.telephony.call_ring.delay is set to 3000 by default anyways
- ro.telephony.call_ring.multiple is not set in stock Samsung ROMs, and
  is defaulted to true in the telephony framework
