Windows,tests: port rule_test_test

Port //src/test/shell/bazel:rule_test_test to
Windows:

- Use the Bash runfiles library (in @bazel_tools)

- Update testenv.sh to retry failed "rm" commands
  because often they attempt to delete a Bazel's
  output directory that is still in the middle of
  shutting down, and just needs a bit of time to
  finish doing so.

See https://github.com/bazelbuild/bazel/issues/4292

Change-Id: I6a7687d15ae3af2ca605149fa75ff48bf2fb89c8

Closes #5490.
