modem: Abstract the list of required ofono interfaces
* We want to add more interfaces to this list when we add more features
(such as waiting for ConnectionManager if we want to use GPRS).
* We want to require some ifaces only if we are planning to use those
features in osmo-gsm-tester (driven by config features attribute set to
the modem in resources.conf).
* Previous usage during shutdown was wrong, as it was waiting for any of
them to be down to continue instead of waiting for all of them to be
down.
