why does child depend on browser?

Haven't started on getting child to actually build yet. Removed that obvious one
though.

i'm a bit confused: why does browser depend on plugin/utility?

No good reason. Mostly just to get something checked in that links. :/ Removed
those two and #if out of chrome_main_delegate, content_main_delegate, and
content_main_runner.
