gsm23003: add osmo_imei_str_valid()
Verify 14 digit and 15 digit IMEI strings. OsmoHLR will use the 14 digit version to check IMEIs before writing them to the DB. Place the Luhn checksum code in a dedicated osmo_luhn() function, so it can be used elsewhere. Related: OS#2541 Change-Id: Id2d2a3a93b033bafc74c62e15297034bf4aafe61
