This breaks multi-python:

The local gen_build_info rule calls into find_cuda_config, which only works in the remote image.

This is additionally brittle: relying on TF_CUDA_VERSION being an action_env is poisoning our caches, and running find_cuda_conifg multiple times is bugprone.

I think the better way to do this is to put the information from the repo_rule into a file template as part of the repo rule configuration (cuda_configure.bzl). Then we can just include that file, instead of trying to do that as part of the action.
