Reduce the number of Chromium dependencies synced.
This should save a bunch of disk space but most important
of all it will not sync the Chromium DEPS-pinned copy of WebRTC,
which can be very confusing when using IDEs that indexes all the
source code recursively.
TESTED=
$ rm chromium/.last_sync_chromium
$ rm -rf chromium/src/third_party/webrtc/
$ gclient sync
Verified chromium/src/third_party/webrtc/ didn't come back.
