tdf#124449: We need also share/gallery for the iOS app

I wonder wheter we should just include all of instdir/share. Seems
that I have to add more and more of it all the time anyway. I don't
remember why I thought (many years ago) that an app would need just a
subset. (Maybe I thought that an app would not, at least not
initially, have functionality that would use most of the stuff in
shre. But that has changed now.)
