main/postmarketos-ui-plasma-mobile: switch to modemmanager (MR 2730)

Upstream has switched from ofono to modemmanager since Plasma 5.23 and
Plasma Mobile Gear 21.12. Since the latter has just been released it's
now time to switch our images too.

The modemmanager service will be enabled to start on default and for
existing installations the .post-upgrade script will disable and stop
the existing ofono service and enable and start modemmanager instead.
