[bazel] Update bazel-toolchains to 4.1.0.
[bazel] Update bazel-toolchains to 4.1.0.

Bazel was upgraded from 4.0.0 to 4.1.0 on our gLinux workstations, which causes "bazel build --config=remote" to fail with an error similar to https://github.com/bazelbuild/bazel/issues/13397.

Upgrading bazel-toolchains to 4.1.0 fixes the above error.

See https://github.com/bazelbuild/bazel-toolchains/releases/tag/4.1.0 for more.
