Subject: modem: Move modem iface to its netns before using it

We used to do that once after ofono startup for all iface
(modem-netns-setup.py), but then if a modem crashes the interface is
re-created on the default netns, and tests fail until manual re-run of
modem-netns-setup.py.

This way now we always make sure the iface is moved to the expected
netns before it is used.
