    build: Allow building grilo as a Meson subproject
    
    If a new enough version of Grilo isn't installed when trying to build
    grilo-plugins, Meson will now automatically clone the repo from Gitlab
    and build that.
    
    This can be disabled with the `--wrap-mode=nodownload` configure time
    option.
    
    Depends on: https://gitlab.gnome.org/GNOME/grilo/merge_requests/50
    and https://gitlab.gnome.org/GNOME/grilo/merge_requests/51
