Original issue's description:
> NaCl: Update revision in DEPS, r13018 -> r13062.
> 
> Chromium NaCl scripts now uses package_version to extract.
> 
> Now that we have split up the toolchain into multiple tars, we should
> use the package versioning script to manage which tars to extract.
> Unfortunately, currently the SDK uses different directory names compared
> to what the NaCl toolchain directories normally use, so we also must map
> and move the toolchain directories to the SDK ones.
> 
> TEST= trybots
