Subject: [PATCH 02/12] test-kernel-commit: Pull in a specific check-config.sh

This makes the package actually build reproducibly, with the downside that it
requires changing the hash. Perhaps this should move to tools/alpine.

Subject: [PATCH 04/12] test-ns: Update DEPS

Makefile and Dockerfile are implicit from pacakge.mk.

Need to list the other files consumed by the Dockerfile though.

template.yml is only for manual testing and so is not a dependency of the
standard build.

with cwd of test this was done with:

Note that `linuxkit/test-virtsock` (built by `test/pkg/virtsock`) does not
appear to be referenced anywhere.
