Modify SI 13 field for control_ack_type
Add vty function to explicitly set use of 4xRACH type of ack message for
PACKET CONTROL ACKNOWLEDGMENT. Previous hardcoded value (use RLC/MAC
control block) is used as a default.
This is handy for debugging issues related to Timing Advance in context
of GPRS.
