Handle newer libhtc_ril.so releases

Querying available networks returns five strings per network instead of
four which breaks that functionality in RILJ. This fix most likely
appiles to every library since Hero.

Disabled per default, define BOARD_USE_NEW_LIBRIL_HTC if you are
building with libhtc_ril.so libraries version 2 and above.
