Michael Stapelberg 013dd178dc all: drop unnecessary import renames for consistency 
Most of our imports already comply with the style, but this change makes it
consistent across the entire repository.

I suspect that these unnecessary imports are left-overs from differences between
Google-internal (where many imports are renamed) and Open Source.
