Android: More input handling tweaks

* Android: Fix #7552 by simply ensuring we drain the input/cmd queue first, simply by scheduling the task to the next tick, instead of locally re-implementing part of the event loop ;). (Requires https://github.com/koreader/koreader-base/pull/1356 for extra safety).
* Android: Clear input state when the window loses focus. (Related to the above fix).

* Bump base:
