Add config_show4GForLte false to US carrier config.xml

By default we now show 4G instead of LTE by changing
config_show4GForLte to true in

So for US carriers we are adding a config.xml which has
config_show4GForLte to false. The list of overlays comes from
looking for mcc=310 & mcc=311 in the apns-conf.xml for vendor deb.
