[bazel] Fix missing @fuchsia_sdk in incremental builds.

In certain conditions, the @fuchsia_sdk repository was not properly
regenerated by Bazel as expected, then Ninja would try to run other
actions that depend on it, such as
//build/bazel/bazel_sdk:bazel_sdk_tests, which would fail horribly
with an error message such as:

```
Build failure: no such package '@@fuchsia_sdk//'....
```

This fixes the issue by using a symlink chain to ensure that
whenever the repository is removed (e.g. after `fx gen`), the
Ninja target will properly run its command to regenerate it,
instead of relying on a stale stamp file.
