[PATCH v20210111 05/39] tools: add with-xen-scriptdir configure option

[Olaf Hering <olaf@xxxxxxxxx>]

In the near future all fresh installations will have an empty /etc.
The content of this directory will not be controlled by the package
manager anymore. One of the reasons for this move is to make snapshots
more robust.

As a first step into this direction, add a knob to configure to allow
storing the hotplug scripts to libexec because they are not exactly
configuration. The current default is unchanged, which is
/etc/xen/scripts.
