NaCl: Update revision in DEPS, r9434 -> r9499

The previous DEPS update was reverted due to failures caused by Gyp
failing to incrementally rebuild some assembly files on Windows and
Mac Xcode.  This should be fixed by r9499.

Hopefully there are no more problems caused by Gyp's incremental build this time
around.
