    flatpak: Update to new gudev's buildsystem
    
    The buildsystem was changed recently from autotools to meson, so it
    no longer builds since the default buildsystem is autotools (when no
    buildsystem is specified).
    
    Hence, this commit switches to the meson buildsystem for gudev.
