android/socket: Include HF AG in built-in profiles

This patch adds entry for HF AG profile in built-in profiles list. This
it to reserve channel number so it's not assigned to other service
registered by application. Method for creating SDP record is not
provided so it's not possible for application to register HF AG service
by mistake (this can be only done by handsfree profile implementation).
