Update mapping for the rat type in data stall proto

Previously, the radio technology definitions are refered to those
definitions in ServiceState. However, the definitions are
slightly different from the definitions of NETWORK_TYPE_* in
TelephonyManager which will cause the data is misjudged. Revise
to refer to the same definitions.
