Add dpranke, scottmg as owners for GN-related files in src/build.

Add dpranke, scottmg as owners for GN-related files in src/build.

Also, remove the 'set noparent'; that was probably useful when
build/OWNERS had a wildcard, but it doesn't any more.

Is it possible to do this but have me be the only owner of BUILDCONFIG.gn? I
can't think of a good way to do this.

Is that what per_file does? If not, I guess re-add noparent, and we can be sure
to pass BUILDCONFIG to you.

Yes, that is what per_file does. I can add that.

Okay, added. Please take another look?

Though I don't really like the idea of *any* file only having one owner. Perhaps
we should discuss what it would take to make you more comfortable with having
other owners for this file, too.

Additions to BUILDCONFIG are almost always wrong and if somebody thinks they
really need to add that I want them to talk to me to see if we can find a better
way.
