Allow deployment of cmdline only projects on Android

Some users might want to develop Qt projects that target Android without any Gui elements, atm this is not possible neither by the Qt for Android plugin nor by the tooling side (i.e. Qt Creator).

This is not possible because of few reasons:

• Qt Android plugin does a bunch of Gui related stuff and thus require Gui dependency
• the same plugin and other Qt Core parts might do some JNI calls which are not necessarily available when running a Qt executable from Android as a cmdline exec.
• Qt Creator supports only androiddeployqt deployments which use Gradle to make an apk which is meant for app with a Gui

So to start supporting a non-Gui cmdline only Qt for Android deployment we need to fix the set of limitations mentioned above.
