    build: fix previous commit and add xdg-config/gtk-3.0 access.
    
    I had an error in the previous commit (2 args in 1). Also adding access
    so that the file `bookmarks` is visible from the contained GIMP
    (otherwise bookmarked folders are lost in flatpak and that's bad
    experience).
