Don't call touch_ui_*() API that are no-ops anyway

Theiry implementations were empty both for iOS (well,
TiledLibreOffice, our iOS test viewer app, anyway) and Android.  Part
of work to make TiledLibreOffice use LibreOffieKit instead of
<touch/touch.h> and the older Writer-specific tiled rendering API.
