Load no-mcc-mnc config for carriers w/o configs

Issue: when carrier config for mcc/mnc 000/000 doesn't exist, no-mcc-mnc
config in vendor.xml is not applied to carriers w/o any customized
configs in assets or vendor.xml.

Solution: Generate a 000/000 carrier if no-mcc-mnc config exists in
vendor.xml, so no-mcc-mnc config will be applied as the default config
for carriers without configs.
