Start to use struct osmo_auth_vector from gsm_auth_tuple

Rather than having a 'private' structure for kc, sres and rand, we
now finally (with 4 years delay) use osmo_auth_vector from libosmogsm,
which encapsulates authentication vectors that can be either GSM
triplets or UMTS quintuples or a combination of both.

gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding
use_count and key_seq to it.

key_seq is no longer initialized inside gprs_gsup_messages.c, as there
is no CKSN / key_seq inside the message anyway.  If a usre of the code
needs key_seq, they need to manage it themselves.
