gbproxy: Parse Detach Request messages

GSM 24.008 also allows a P-TMSI field in Detach request messages.

This patch adds gbprox_parse_gmm_detach_req() to parse Detach Request
messages which sets the ptmsi field if the IE is present.

In addition, when power_off is set to 1 (MO only), the
invalidate_tlli field is set, since Detach Request message is
expected in this case.

The second detach test (see 'RA update') is modified to use
power_off instead of relying on a Detach Accept from the network.
To make this work, the PTMSI of the RA Update Accept is fixed to
match the TLLI of the Detach Request.
