Since usb-moded is using Type=Notify, specifying a BusName leads to
systemd complaining: "usb-moded.service: Service has a D-Bus service
name specified, but is not of type dbus. Ignoring."

Remove BusName specification from the usb-moded.service file.

Systemd environment files can't be used to accumulate values and the
existing $USB_MODED_ARGS is already used for the purposes of optional
rescue mode.

Use separate $USB_MODED_HW_ADAPTATION_ARGS to allow passing hw adaptation
specific command line options to usb-moded.

Additionally remove the '-a' argument from default command line parameters
as it can now be handled in adaptation config only for those devices that
actually need it.
