Add xentools418 version 20231116
Unlike previous Xen packages, the xentools418 and xenkernel418 will point
to a specific commit of the stable branch (instead of release tags),
the package version being the date of the commit. Hopefully this will make
tracking security fixes easier.

tools to create, destroy and control the virtual machines.

This package contains the tools for Xen 4.18.x
