ts_31_102: Add "ust_service_check" command.
This command performs a consistency check between the services activated in EF.UST/EF.IST and the files that should (or should not) be active/selectable for the given service. Produces output like: Checking service No 48 (inactive) ERROR: File EF(EF.MWIS) is selectable but should not! Checking service No 49 (active) ERROR: File EF(EF.CFIS) is not selectable (SW=6a82) but should! Change-Id: Iea7166959e2015eb8fa34d86036560c9e42ce4d3
