[meta-zephyr,1/2,kirkstone] CI: Add variables needed for k8s runners

From: Peter Hoyes <Peter.Hoyes@arm.com>

The Kas container needs to use the entrypoint as that is where the user
changes from root to a normal user.

Also set the KUBERNETES_CPU_REQUEST to the variable CPU_REQUEST as this
needs to be tuned per-deployment.

CPU_REQUEST has no value outside of Arm Corp.  Gitlab CI allows for
variables to be overridden by default.  So, we can give it a default
value of NULL/empty and have everything work internally and externally
by default.
