guix: Rewrite build-docker-image to allow more paths.
* guix/docker.scm (build-docker-image): Rename "path" argument to
  "prefix" to reflect the fact that it is used as a prefix for the

  argument.

  graph and provide its paths to build-docker-image via the new "paths"
  argument.

environment: Add --user.
This change allows overriding the home directory of all filesystem mappings to

Mike Gerwitz 07ec349229
environment: Add --link-profile.
This change is motivated by attempts to run programs (like GNU IceCat) within
containers.  The 'fontconfig' program, for example, is configured explicitly
to check ~/.guix-profile for additional fonts.

There were no existing container tests in 'tests/guix-environment.sh', but I
added one anyway for this change.

* doc/guix.texi (Invoking guix environment): Add '--link-profile'.
* guix/scripts/environment.scm (show-help): Add '--link-profile'.
(%options): Add 'link-profile' as '#\P', assigned to 'link-profile?'.
(link-environment): New procedure.
(launch-environment/container): Use it when 'link-profile?'.
[link-profile?]: New parameter.
(guix-environment): Leave when '--link-prof' but not '--container'.  Add
'#:link-profile?' argument to 'launch-environment/container' application.
* tests/guix-environment-container.sh: New '--link-profile' test.

offload: Fix regression in file retrieval.
This fixes a regression in 'retrieve-files*' introduced in
896fec476f, whereby (guix scripts offload)
would not read the initial sexp now sent by the remote host via

entirely when offloading.
