The vmlinux image is the un-stripped kernel image containing
full debug information which is useful for kernel debugging.

Building debug kernels (with additional run time checks and debugging)
was broken a few commits back. This adds back support for building debug
kernels.
In addition, it builds and uploads debug kernels for selected kernel
series (4.9.x LTS and latest stable). The tag for these kernels has
a "_dbg" suffix.
Update documentation.

- Use a RUN command per artefact created
- Use WORKDIR to avoid "cd /linux" on every RUN command
- Copy all relevant build artefacts to /out
- Only create one additional layer in final stage
- Add System.map to output image

Previously we hardcoded `bzImage` which is not used for all
use cases or architectures.

- Use multi-stage builds
- Use a single Dockerfile for all kernels
Kernel version and series are passed in as arguments
- Use a separate kernel config per kernel version
These have been copied from kernel_config and ran
through oldconfig to tidy them up
- Rename patch directories
- Refactor the Makefile to use a template
- Allows building of all kernels without arguments to make
- Use git tree hash as the image tag
- Don't build the image if the tag already exists

Unused. This should not affect anything, and I didnt actually bump
the kernel version; am working on te build in CI for this...
