Android: Fix use_local_libs when running from launcher

The old way of passing the use_local_libs settings to the
app (which is still supported for compatibility with Necessitas)
was to pass it as command line arguments when the app is
launched from Qt Creator. This will make the app depend on
Ministro if it's later launched from the Android launcher.
To avoid this, we pass the info as part of AndroidManifest.xml
instead.
