gofmt: apply gofmt -w -s src misc

Preparation for forthcoming CL 6624051: Will make it
easier to see if/what changes are incurred by it.

The alignment changes in this CL are due to CL 6610051
(fix to alignment heuristic) where it appears that an
old version of gofmt was run (and thus the correct
alignment updates were not done).
