Since Ministro no longer work on recent Android versions (Android 8+),
and it hasn't been maintained and the repos are not updated, the
existing code is practically a dead code.

and not working with recent Android versions.

Task-number: QTBUG-85201
Pick-to: 6.2
Change-Id: I18d7b1e209cba3cfd04674060e9bf39aa5a5510f
