Subject: [PATCH] import: print: Properly render packages with origins as
 inputs.

* guix/import/print.scm (package->code)[source->code]: Check whether
VERSION is true before calling 'factorize-uri'.
[package-lists->code]: Add clause for inputs that are origins.
* tests/print.scm (pkg-with-origin-input, pkg-with-origin-input-source):
New variables.
("package with origin input"): New test.
