[android] Don't call invalidateInput on old SDKs

Carsten Hartenfelsrequested to merge
hartenfels/qtbase:feature/invalidateinput into krita/5.15

Because it's only available since Android 13. I must have misread the API version as 3 instead of 33, like it is for restartInput. I double-checked the other functions being called, those don't seem to be too recent.
