With:
$ go get -u github.com/LK4D4/vndr
$ sed -i 's/9a7256cb28ed514b4e1e5f68959914c4c28a92e0/a55a76086885b80f79961eacb876ebd8caf3868d/' vendor.conf
$ vndr
I'm not sure why vndr is messing with github.com/golang/protobuf, but
I assume it knows what it's doing.
The x/sys bumps to master, but I need it for MS_LAZYTIME (added in
github.com/golang/sys@ea9bcade75, unix: generate all Linux go files
from source, 2017-03-08).
