    opkg-utils: clear update-alternatives database on uninstall
    
    When uninstalling update-alternatives, it doesn't seem to
    make much sense to keep the update-alternatives database
    around.
    In particular when removing packaging data, e.g. due to
    read-only rootfs, update-alternatives is removed from
    the target file system. Leaving its database around
    serves no purpose in that case as there is no way to
    use it afterwards anyway.
    
    This frees close to 700KB of (uncompressed) space in
    a busybox based environment.
