Revert of NaCl: Update revision in DEPS, r13679 -> r13687

Revert of NaCl: Update revision in DEPS, r13679 -> r13687 (patchset #1 id:1 of https://codereview.chromium.org/537003002/)

Reason for revert:
This breaks NaCl SDK tests on mac (presumably because that's the only one using the 32-bit IRT). See https://code.google.com/p/nativeclient/issues/detail?id=3935
