helpers-qmi: fix detection of primary active SIM status

The original logic that parsed the 'UIM Get Card Status Output' did a
bit of guessing to decide what was the current lock status to consider
in the modem. This guessing was fine on systems with a single SIM
slot, but it was very wrong as soon as multiple SIMs had to be
considered.

In a Multi-SIM Multi-Standby setup, with multiple SIMs reported as
active, we should look for the one flagged as "GW primary" to consider
it the primary SIM card of the system,the one required to start a data
connection.

We explicitly ignore the ones flagged as "1X primary", as we don't
consider a SIM card required in CDMA/EVDO setups.
