Fixes a regression introduced in
d4d7d70912642be18d93c9ce6470f8650097b5e5 which broke
'hunspell-dict-en' (but not the 'hunspell-dict-en-*' variants.)

Suggested by Andy Wingo <wingo@igalia.com>.

Reported by Myles English <mylesenglish@gmail.com>.

* guix/ssh.scm (retrieve-files*): Move error reporting to...
(report-guile-error, report-module-error): ... here.  New procedures.

'report-module-error'.

offload: 'test' gracefully handles 'node-repl-error'.

Fixes <https://bugs.gnu.org/28057>.
Reported by Ricardo Wurmus <rekado@elephly.net>.

* guix/scripts/offload.scm (assert-node-has-guix): Catch
'node-repl-error' and call 'leave'.

* guix/ssh.scm (retrieve-files): Remove the subset of FILES that is
valid in LOCAL.
(store-export-channel): Add comment.

offload: Fix regression in file retrieval.

This fixes a regression in 'retrieve-files*' introduced in
896fec476f728183b331cbb6e2afb891207b4205, whereby (guix scripts offload)
would not read the initial sexp now sent by the remote host via
'store-export-channel'.  This would effectively prevent file retrieval
entirely when offloading.

* guix/ssh.scm (retrieve-files*): New procedure, like former
'retrieve-files' but with an extra #:import parameter.
(retrieve-files): Rewrite in terms of 'retrieve-files*'.
