    build: Allow building grilo as Meson subproject
    
    This change makes it easier to build and test Totem on systems which
    have an old version of Grilo installed. Meson will now automatically
    clone and build the latest Git version of grilo if the system-installed
    version is too old.
    
    Distributors can disable this behaviour by passing
    `--wrap-mode=nodownload` at configure time.
