cosmetic: rename struct osmo_msc_data to bsc_msc_data

With the OsmoMSC program coming up, the name osmo_msc_data becomes even
more confusing than it already is. Clearly indicate it as libbsc's data of
a remote MSC by prefixing with bsc_.

Also, the Osmocom community has in the meantime agreed to have the osmo_
prefix only in libosmocore, to avoid naming conflicts in case things are
moved there. So while renaming anyway, also drop the osmo_ prefix.
