Port to new libosmogsm 'struct osmo_sub_auth_data2'

libosmogsm has recently introdcued a 'struct osmo_sub_auth_data2' as
successor to 'struct osmo_sub_auth_data', together with updated
osmo_auth_gen_vec2/osmo_auth_gen_vec_auts2 API.

The rationale of this new API is to enable
* support for AKA algorithms which use K and/or OP[c] values of 256bit
  (instead of the classic 128bit)
* support for RES length sizes of 4 and 16 bytes (instead of the classic
  8 bytes)

This commit just jumps over to the new API without adding any related
functionality to osmo-hlr.  The latter is left for subsequent commits.
