    meson: Install generated headers without needing a script
    
    This script dates from a long time ago when Meson lacked ways to install
    generated headers.
    
    This fixes an issue where `ninja install` in tracker.git triggers a
    rebuild of lots of stuff from tracker-miners.git, which happened because
    the mtime of the installed generated headers would become newer than the
    build files in tracker-miners.git and cause ninja to rebuild them all.
