    build: Reintroduce enable-gvfs-metadata option
    
    Gedit used to have an enable-gvfs-metadata to enable using gvfs to store
    metadata. This option was removed with the port to meson. Reintroduce it and set
    the default to 'auto' (defaults to 'yes' when running in linux, to 'no'
    otherwise).
    
    Closes: https://gitlab.gnome.org/GNOME/gedit/issues/141
