Update Gopkg.toml to remove spf13 git hash 👼

[vdemeester]

• spf13/cobra is not used at all (not present in the lock or in the
  vendor folder) and the fix Add support for ignoring parse errors spf13/cobra#662 is released too (so
  dep would pick up if we depend on it.
• spf13/pflag 1.0.3 is more recent than the toml git hash 👅

Thanks for the cleanup @vdemeester ! How'd you discover it wasn't in use? Any recommendations on how we can make sure we won't leave around deps we don't need?

I vaguely remembered I did the same on knative/build a while ago 😅 and it's not present in the Gopkg.lock file, so it's not in use 👼 We may want to look into setting up some bot work (à-la @mattmoor @mattmoor-sockpuppet 😝), that would check those, but I don't think it's gonna happen too much in the project lifecycle.
