[bug#42885] [PATCH 06/27] gnu: python-pyqt: Fix build for new python-sip.

[Brendan Tildesley]

* gnu/packages/qt.scm (python-pyqt)
[source]: Remove pyqt-public-sip.patch. PyQt uses python-pyqt5-sip
now. This patch is still used by python2-pyqt so we don't delete it completely.
[inputs]: Add python-pyqt-builder, python-pyqt5-sip
[arguments]: Add phase to link PyQt5-sip module.
