rsl: use 3GPP assigned payload type numbers

The payload types for AMR, EFR, and GSM-HR are dynamic payload types. In
theory those can have any number from the IANA reserved dynamic payload type
rante. However 3GPP TS 48.103 assignes AMR, EFR and GSM-HR a fixed payload type
number from the dynamic payload type range. Lets make sure our payload types
use the 3GPP payload type numbers instead of arbitrary choosen ones.

- change payload type define constants to match 3GPP TS 48.103
