    Install plugins to subdirs.

    install_dm_plugin  install files to libdir/device-mapper
    install_lvm2_plugin install files to libdir/lvm2

    Both targets creates relative links to libdir to keep the code
    compatible with current dlopen handling.

    Once we will be able to read plugins from subdir, links
    could be removed.
