sh_binary rule for windows is incorrectly trying to resolve symlinks during remote execution

On windows the sh_binary rule is incorrectly trying to resolve symlinks directly, causing paths to not be correct on the re environment that we have setup:

https://github.com/facebook/buck2/blob/2214ec241cefe357faf499e30b26629ce6728c8c/prelude/sh_binary.bzl#L92

As you can see, this ends up traversing to the parent on the cache, which doesn't translate to it being the parent directory of the other files:

```

```

This specific step should be removed, or made configurable via an attribute on the rule. Happy to submit a fix for this
