third_party/linux: build using unhermetic rule
This replaces ad-hoc genrules (for the node Linux image and the ktest
image) with a real Bazel rule with an attached transition which ensures
we end up with the same-ish configurations for all builds of an image.
This reduces rebuilds of the ktest Linux kernel, from three down to one.

After: https://drive.google.com/file/d/13eO1rLhoBCMMRUKrmJz8QnhdAR3ctIGb/view
We also drive-by fix the Kubernetes CTS test suite to run on a single-node
Cluster (instead of failing early due to that being currently reworked).
Test Plan: Build system refactor, following existing test.
