[PATCH v20210209 2/4] tools: add with-xen-scriptdir configure option

[Olaf Hering <olaf@xxxxxxxxx>]

Some distros plan for fresh installations will have an empty /etc,
whose content will not be controlled by the package manager anymore.

To make this possible, add a knob to configure to allow storing the
hotplug scripts to libexec instead of /etc/xen/scripts.

The current default remains unchanged, which is /etc/xen/scripts.
