Update clang-format binaries and scripts for all platforms.

I followed these instructions:
https://chromium.googlesource.com/chromium/src/+/master/docs/updating_clang_format_binaries.md

The binaries were built at clang revision 293675 on Fri Feb 17 17:17:17 PST 2017.

Results/diagnostics on clang-format binaries:
-> old/current: https://codereview.chromium.org/2700123003/
-> new: https://codereview.chromium.org/2701993002/

Also checked that the uploaded Mac and Linux binaries have the
executable bit and that Mac binary is targeting OSX 10.9.
