Roll chromium_revision 6455c69..deaf2f7 (293954:295079)

Mainly to pick up recent yasm changes needed for
turning on libvpx in GN.

Summary of changes (git diff 6455c69..deaf2f7 DEPS):
* third_party/boringssl 7bdec13..a70c75c

* third_party/libvpx d95585f..4947d55

I had to add src/third_party/junit/src to be ignored
due to http://crbug.com/417292.
