Treat registrations to operators in the SPDI list as non-roaming

There are multiple virtual operators which don't have their own networks, and re-use networks from other providers. When using a SIM card from one of these virtual operators, ModemManager will show in the 3GPP registration info the service provider network (i.e. the operator name/MCCMNC of the network in which the device is registered), and it will also show the registration as roaming. It technically is roaming; but logicaly isn't, as the network to which the device is registered is to be treated as 'home'.
So, registrations to networks available in the SPDI list of the SIM card (list which provides home-like networks) shouldn't be marked as roaming; and the User Interface should follow the rules marked by the SIM card to decide which Operator Name to show in the interface (either the name of the operator which issued the SIM card or the name of the SPN).
Work to start handling this is already available in the 'aleksander/display-rules' in git, see: http://cgit.freedesktop.org/ModemManager/ModemManager/log/?h=aleksander/display-rules
