gitlab-system: Also strip CPU requests from init containers.

The Assign only covered spec.containers, so each GitLab pod still
requested 50m through its init containers (effective request is the
larger of the biggest init container and the sum of containers).  This
made new pods unschedulable during the 10.5.4 rollout at ~86% CPU
requests.
