Obtain region config from system-property for Contacts pre-loading

If Telephony isn't ready during the first boot, then the Resource
configuration for Contacts pre-loading does't have the right
information to determine whether or not to add the default contacts.
This patch adds a check on the "ro.prebundled.mcc" system-property
to help determine the region specific configuration to use.
