[AWARE] Configure the subscribe information in beacons

HAL (HIDL) contained configuration of subscriber ID in
discovery beacons (useful for higher probability of
discovery, better cluster selection & merging).

This CL modifies the implementation of the HAL to set
the (new) legacy HAL hooks from the HIDL values.
