move to libxsc: gsm48_create_mm_serv_rej(), gsm48_create_loc_upd_rej()

Used by libbsc, libmsc as well as osmo-bsc and osmo-bsc_nat.

Moving gsm48_create* to libxsc affects linking of osmo-bsc_nat, resulting in
undefined references to gsm48_extract_mi() and gsm48_paging_extract_mi(); fix
that by placing libfilter.a left of libbsc.a upon linker invocation.
