I sent a v2 with some of the style changes applied.  It seems that
across guix the more common approach is to put (modify-phases) under the
#:phases keyword, and I prefer it.

In general I do not believe what `guix style' did to the (arguments) let
to more readable code, so I left it as it was.

I did adjust the (source) and (description) though.

I tested the pasta binary instead using podman (--network=pasta), since
it was the reason I added this package in the first place.  It worked.
