fix compiler warnings with new libosmo-sccp: rename to osmo_sccp_*

See libosmo-sccp.git 1a3875092f93df3c3054d26eac52bb0ea9bd09c3

Note: at time of commit, osmo-iuh still depends on the libosmo-sccp sysmocom/iu
branch to build.

The same rename has been committed to both sysmocom/iu and master on
libosmo-sccp. Above commit hash is on sysmocom/iu. The master commit is
03ad002c28073b347b92bcde16d5af80a06389e4.
