Remove references from blink/public to non-existing headers

An android specific block in BUILD.gn kept some references to
files that no longer existed after a cleanup in
https://chromium-review.googlesource.com/896839

This caused some local issues with trybots so it was time to
clean up the build files. Bye unnecessary code block.
