[bug#63053] [PATCH 0/3] Fix "guix import crate"

[Simon Tournier <zimon.toutoune@gmail.com>]

Hi,

Consider,

--8<---------------cut here---------------start------------->8---
$ guix import crate non-existent
guix import: error: failed to download meta-data for package 'non-existent'
--8<---------------cut here---------------end--------------->8---

and then,

--8<---------------cut here---------------start------------->8---
$ guix import crate non-existent -r
Backtrace:
           5 (primitive-load "/home/simon/.config/guix/current/bin/guix")
In guix/ui.scm:
   2300:7  4 (run-guix . _)
  2263:10  3 (run-guix-command _ . _)

guix/import/utils.scm:630:33: In procedure lookup-node:
Wrong number of values returned to continuation (expected 2)
--8<---------------cut here---------------end--------------->8---

as reported by #63030 [1].  This patch set fixes that.

Note that ’guile-semver’ is already part of ’self’ but not part of ’guix’,
therefore “guix shell -D guix” does not provide the necessary guile-semver for
testing with ./pre-inst-env.

  guix: import: crate: Fix incorrect returned values.
  scripts: import: crate: Handle non-existent package.
