[bug#74500] pack: add ‘--file=FILE’ with the same meaning as for guix build

["Dr. Arne Babenhauserheide via Guix-patches" via <guix-patches@gnu.org>]

[-- Attachment #1.1: Type: text/plain, Size: 283 bytes --]

Hi,

the attached patch adds the option to use `guix pack --file=guix.scm` just
like you’d use `guix build --file=guix.scm` or `guix shell
--file=guix.scm`.

guix pack -f ... still means --format to preserve backwards
compatibility. Only the long option --file is added.

* guix/scripts/pack.scm (%options): add --file=FILE, but no
  shorthand (that’s already taken for format).
* doc/guix.texi (Invoking guix pack): document --file
