download_and_extract() doesn't create subdirectories specified in "output" argument

[steven-johnson]

given

output = "my_subdir"
repository_ctx.download_and_extract(url, output, sha256, type, strip_prefix)

this will generally fail (on Bazel OSX 0.22) because "my_subdir" doesn't exist in the newly-created cached dir, and download_and_extract isn't creating it.

Note that you can work around this by using

repository_ctx.file("my_subdir/empty_file", "") 

beforehand.

Oh I though I filed a bug about that. Yes download and download and extract should create the necessary folder.
