handle an empty list.

Fixes: &lt;https://issues.guix.gnu.org/62781&gt;

* guix/build-system/pyproject.scm (lower): Change default of configure-flags.
* gnu/packages/build-tools.scm (meson-python)[arguments]: Remove #:build-backend,
which was a workaround for this bug.
[native-inputs]: Remove python-p~a-build and python-wheel, which are
not required when using the default build system.
