Subject: [PATCH] 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")
