[bug#38312] [PATCH 2/3] Use 'offload?' instead of 'build-hook?' internally.

[Ludovic Courtès]

* guix/scripts/archive.scm (%default-options): Replace 'build-hook?'
with 'offload?'.
* guix/scripts/build.scm (set-build-options-from-command-line): Pass
 #:offload? instead of #:use-build-hook?.
(%standard-build-options): Use the 'offload? key instead of 'build-hook?.
(%default-options): Replace 'build-hook?' with 'offload?'.
* guix/scripts/copy.scm (%default-options): Likewise.
* guix/scripts/deploy.scm (%default-options): Likewise.
* guix/scripts/environment.scm (%default-options): Likewise.
* guix/scripts/pack.scm (%default-options): Likewise.
* guix/scripts/package.scm (%default-options): Likewise.
* guix/scripts/pull.scm (%default-options): Likewise.
* guix/scripts/system.scm (%default-options): Likewise.
* guix/scripts/time-machine.scm (%default-options): Likewise.
* guix/store.scm (set-build-options): Have #:use-build-hook? default
to *unspecified*.  Add #:offload?.  Add call to 'warn-about-deprecation'
when #:use-build-hook? is specified.
