Fixes <https://bugs.gnu.org/38196>.
Reported by Florian Pelz <pelzflorian@pelzflorian.de>.

* guix/scripts/system.scm (maybe-suggest-running-guix-pull): Check
whether 'current-profile' returns true instead of checking for the
existence of ~root/.config/guix/current.  That way, "sudo guix system
reconfigure" no longer emits a warning in that case.

* gnu/packages/autotools.scm (automake-1.16.2): New variable.

* guix/scripts/pack.scm (squashfs-image)[build](mksquashfs): Pass "-no-xattrs".

It also removes the store file name from the output.

* guix/ui.scm (show-manifest-transaction)[package-strings]: Rewrite to
use 'tabulate'.  Remove 'item' parameter and adjust callers.

This also changes "1.0.0 → 1.0.0" to "(dependencies changed)", which is
probably less confusing.

* guix/ui.scm (tabulate): New procedure.
(show-manifest-transaction)[upgrade-string]: Rewrite to take lists of
names, versions, and outputs instead of single elements.  Use
'tabulate'.  Adjust callers accordingly.

* guix/import/crate.scm (crate-version-dependencies): Deduplicate crate dependencies.
