xwayland: Add XWayland by adding x11 to DISTRO_FEATURES
Usually, it should be sufficient to add x11 to the DISTRO_FEATURES. However, this breaks vim somehow. Probably due to missing gtk+3 dependencies.
Thus add a vim bbappend file and force PACKAGECONFIG to ignore x11 and gtkgui and only use the acl package configuration.
