altair-lte: obtain subscription state of SIM from registration failure code

This patch uses the extended error code after a registration failure to
determine if the SIM in the relevant modem is associated with a non-provisioned
account. It uses the standard AT+CEER command, but the implementation is
restricted to the altair plugin.
