Chromium NaCl scripts now uses package_version to extract.
Updates NaCl revision from 13106 -> 13115
This CL reverts revision 266284.
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.
