Only exclude disk_cache from remote execution (#6886)
Turns out disk_cache is allowed with a remote cache:
https://github.com/bazelbuild/bazel/commit/76370d5453. It's only remote
*execution* that is currently incompatible (although compatibility was
recently added).
Tested: ran a local build with remote and disk cache.
