Doc package change done long time ago and installations have migrated.

Also rpm from 2013 is no longer 'reasonably fresh'.

Had Android device paired via bluetooth to Sailfish one, then
disconnected them. A hfp modem was created which stayed offline.

That's a problem of its own, but amplified by connman trying every 2
seconds to make the modem go online. That's doomed to fail as long
as it's not powered. Thus, if set_powered fails, the online attempts
are stopped.
