Godeps: Try to appease CI by mimicking comment diff.

Prior to this commit the builds of master are failing in Travis with an
error during the `godep-restore` phase of our CI:

```
[   godep-restore] Starting
godep restore
rm -rf Godeps/ vendor/
godep save ./...
diff /dev/fd/63 /dev/fd/62
254c254
<                       "Comment": "v1.3-28-g3955978",
---
>                       "Comment": "v1.3.0-28-g3955978",
>                       git diff --exit-code -- ./vendor/
>
```

This seems to be a mysterious difference in the "Comment" field of the
`github.com/go-sql-driver/mysql` dependency. This dep hasn't changed
versions so given the general level of frustration involved with
debugging Godep it seems like the easiest path forward is to mimick the
diff.

This commit updates the "Comment" filed to match what CI expects.
