mgcp: Move Annex A counting out of patch/count method

mgcp_patch_and_count has grown due supporting linearizing timestamps,
ssrc and other things for equipment like the ip.access nanoBTS. Fight
back and move the Annex A code into a dedicated method.

The result is updated as we now count after all the patching and for
the Annex A code no change in SSRC can be detected.
