Remove spaces from APN types read from the file

APN types are parsed from apns-conf.xml and could contain
spaces. Remove the spaces from the types field before using it.

Bug: 33234377
Test: Add spaces between types in apns-conf.xml for verizon
      "internet" APN and send MMS. Device was able to send
      MMS successfully using the "internet" APN on 1X.
