Enable auto select only when set by Carriers

Carriers want to avoid users from setting other
networks than their own when in the home network.
This is in some implementations called
"Permanent automatic mode".

Test: Add an entry for carrier X in vendor xml and see
the Settings entry change when you swap sim cards between
carrier X and Y.
