Compilation breaks when compiling v8 through Chromium using GYP. The isssue
started to appear after https://codereview.chromium.org/2190973003 landed.
It happens because trace_event_common.h header is on different location if we
are compiling v8 through Chromium compared to when we are compiling v8 standalone.
