Remove unused bit from bazel.patch
Remove unused bit from bazel.patch

Summary:
Remove `bazel` target modification from `bazel.patch` (because this target is not used in build) to increase probablility of successful application of patch when upgrading bazel to new version.

Also regenerate the patch with

```
git apply < .../bazel.patch
```

```
git diff 'HEAD^..' > .../bazel.patch
```

inside bazel repository in revision specified in `COMMIT_HASH.facebook`.

This work is done to be able to upgrade Starlark implementation from upstream easily.
