Rename exec_tools to tools

Follow up to tensorflow#43156
Based on
bazelbuild/bazel#12059 (comment)
exec_tools might no longer be needed and hence can be replaced by tools.
This fixes various build failures caused by missing environment
variables in environments where they are required, e.g. using custom
compilers.
