[bug#49169] [PATCH v2 13/16] import: pypi: Emit new-style package inputs.

["Ludovic Courtès" <ludo@gnu.org>]

* guix/import/pypi.scm (maybe-inputs): Wrap PACKAGE-INPUTS in 'list'
instead of 'quasiquote'.
(compute-inputs)[requirement->package-name/sort]: Return a list of symbols.
* tests/pypi.scm ("pypi->guix-package, no wheel")
("pypi->guix-package, wheels"): Adjust accordingly.
