broadband-modem: parse +GSN response for IMEI, MEID, and ESN (bgo #696596)

+GSN response differs widely between modems.  Some prefix the
MEID and/or ESN with 0x, some have leading zeros, some return the
MEID and the ESN, and some append the serial number to the end of
the IMEI.  Handle that and make the ESN, MEID, IMEI, and
EquipmentIdentifier parsing consistent.
