[osmo-bts PATCH 3/5] utils: Changed the function check_oml_message for returning message vendor type

From: Álvaro Neira Ayuso <anayuso(a)sysmocom.de> Added some changes for returning the vendor type of message that we have checked. We are going to return OML, Manufacturer O&M Ipaccess message or Manufacturer O&M osmocom message. BTW, I have fixed a wrong use of sizeof in the code that I have modified.
