Rolf Neugebauer bdd4789598 kernel: Fix docker content trust for perf builds
Due to https://github.com/moby/moby/issues/34199 we can't supply
the FROM image via --build-arg and use DOCKER_CONTENT_TRUST=1 for build.

So we pull the image with DCT and then explicitly build it without.

This regression was introduced with 8b84baf2 ("kernel: Allow disabling content trust")

See ../docs/kernel-patches.md for more information on kernel builds.

To build with various debug options enabled, build the kernel with make DEBUG=1. The options enabled are listed in kernel_config.debug. This allocates a significant amount of memory on boot and you may need to adjust the kernel config on some systems. Specifically:
