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

the kernel version; am working on te build in CI for this...
