Improve YouCompleteMe handling of Blink header without source files.

Improve YouCompleteMe handling of Blink header without source files.

In this case, simply giving the Chromium src root as the include path
is unlikely to be helpful. We can get a pretty close approximation by
getting the flags for an arbitrary Blink source file, which will have
more reasonable include paths and defines for a Blink header.
