[bug#42885] [PATCH 23/27] gnu: calibre: Update to 5.13.0.

[Leo Famulari]

While testing the dependents of packages changes in this patch series, I
found that QGIS fails to build as a result of these patches, like this:

I think the salient part is near the beginning:

.sip5-real: Unable to find file "QtXml/QtXmlmod.sip"

I tried using your original approach for pyqt5-sip, where you symlinked
it into the output of python-pyqt, but I got the same result.

I guess that we need to adjust the package python-pyqt+qscintilla. Any
ideas?
