Remove self included headers

I found this while looking at the #include dependency graph for
browser_tests. I would guess these all got added when they got
de-virtualized; https://crrev.com/c/854747 was one such CL, and
it looks like they copy pasted a lot of the code, which probably
meant the self includes were accidentally added.
