Hello!

Until now, we’d be building channel modules with the calling Guix
rather than with the Guix of the 'guix channel we’re targeting.
That led to breakage, for instance, when we added new dependencies
to Guix itself and the channel modules would thus not see them; see
commits 3c0e16391ed9a3e3e4611b940fb393c5f2ecea63 and
cb341c121919877ae6267a6460c0c17536d06eff.

These patches fix that.

Ludo’.

  channels: Don't pull from the same channel more than once.
  inferior: 'gexp->derivation-in-inferior' honors EXP's load path.
  channels: Build channel modules in an inferior.
