shepherd -> guile 2.2?

[Ricardo Wurmus]

Hi Guix,

I have built shepherd with guile-2.2, but I noticed a couple of
warnings/errors during the build:

Is this bad?  Should I do something to avoid this?
And lastly: should we keep a guile-2.0 variant of the shepherd, or is it
fine to push this tiny change?
