    install.sh: Preserve symlinks in destination file system
    
    In various distros (i.e. Debian), /lib is a symbolic link. The tar
    command in install.sh replaces the /lib symlink with a directory and
    results in a non-functioning system. This has been introduced by the
    installation of the systemd watchdog sleep script in /lib/systemd.
    
    This patch adds the tar option --dereference (-h for short) to preserve
    symlinks when extracting the dist archive.
    
    Fixes: e54a6cd6a1f3 ("systemd: Add hooks to stop/start xen-watchdog on 
suspend/resume")
