android: Don't mark doc changed on keypress in readonly mode

Since input etc. is otherwise ignored in readonly mode,
also don't mark the document as changed on keypress.

This e.g. avoids an unnecessary dialog whether or not to
save the document after opening a document with experimental
editing mode disabled, then pressing a key (on hardware
keyboard, soft keyboard isn't shown in readonly mode)
and then pressing the "Back" button to close the document
again.
