undo CL 84040045 / 5302b4c58aa0

This idea was rejected in CL 5731059. We should fix the
runtime docs instead.

««« original CL description
cmd/dist: reflect local changes to tree in goversion

runtime.Version() requires a trailing "+" when
tree had local modifications at time of build.

Fixes #7701
