move GSM_RESERVED_TMSI to libosmocore

The gb_proxy shouldn't start to open the box of pandora by including the
gsm_data_shared.h file, particularly not without defining the BSC role.

In any case, as the reserved TMSI is something that's part of the GSM
specs, and not specific to the OpenBSC implementation, it should be part
of libosmocore.
