tdf#129833 android: Drop non-working ownCloud/nextCloud support

As mentioned in tdf#129833 comment 3, the idea is to
use Android's "system file dialog" to select files rather
than maintain a separate ownCloud/nextCloud connector in the
Android Viewer app.
This way, everything for which a DocumentsProvider [1] is
available will be available from within the app, once
Android Viewer has been adapted to support those, which is
planned for a subsequent step.

Corresponding DocumentsProviders for ownCloud [2] and nextCloud [3]
exist.

[3] https://github.com/nextcloud/android
