gsup: add OSMO_GSUP_SUPPORTED_RAT_TYPES_IE and OSMO_GSUP_CURRENT_RAT_TYPE_IE
OSMO_GSUP_SUPPORTED_RAT_TYPES_IE corresponds to the Supported RAT Types
Indicator from 3GPP TS 29.002. See 8.1.2 MAP_UPDATE_LOCATION service,
which indicates the capabilities of the MSC/VLR to the HLR.
So far, have room for eight RAT types in the gsup_msg. That is an arbitrary
random choice without any rationale.
OSMO_GSUP_CURRENT_RAT_TYPE_IE is useful to communicate the currently
used RAN / RAT type of the current subscriber during Location Updating Request.
