Bazel client: simplify ReadDirectorySymlink
This is a bugfixed version of
https://cr.bazel.build/9520 which broke some
Google-internal tests.
This change allows removing duplicate code:
ReadDirectorySymlink was implemented on Windows as
a junction resolver, which is also implemented in
file_windows.cc. Now it uses the JunctionResolver.
