Revert of Changes exception for gyp files to only gyp files in build/ (patchset #1 id:1 of https://codereview.chromium.org/512693004/)

Reason for revert:
gyp change this depended on was reverted

Original issue's description:
> Changes exception for gyp files to only gyp files in build/
>
> I changed analyzer such that if a gyp file (or an included gypi file)
> changes all targets in the gyp file are marked as changed. This means
> I should no longer have to special case gyp files. I'm leaving the
> exception in place for any gyp files in build as any change to those
> really needs to recompile the world.
