[bug#58020] [PATCH] import/utils: alist->package: Include properties.

[itd <itd@net.in.tum.de>]

* guix/import/utils.scm (alist->package): Process properties field in input
data and include it in the generated package.
* tests/import-utils.scm ("alist->package with properties"): New test.
---
Hi,

this patch enables the JSON importer to include package properties in its
output and a test to check that the modified function's result is consumable by
functions that use these properties.
Please consider applying it.  Thanks!

Regards
itd
