gnu: calibre: Update to 5.14.0.

* gnu/packages/ebook.scm (calibre): Update to 5.14.0.
[source]: Adjust the snippet to preserve some files used by the HTML reader.
[native-inputs]: Add python-pyqt-builder. Replace python2-flake8 with
python-flake8.
[inputs]: Remove chmlib, js-mathjax, python-chardet, and python-sip.  Add
python-cchardet, python-speechd, python-zeroconf, python-py7zr, python-pychm,
python-pycryptodome, libjpeg, and libjxr.  Replace all Python 2 dependencies
with their Python 3 equivalents.
[arguments]: Build with the default Python and adjust custom phases accordingly.
Adjust the 'configure' phase to changes in how Calibre uses SIP, and patch
lookup paths for libjpeg and libjxr.
Rename the 'build-extra' phase to 'install-rapydscript', and run it after the
'install' phase. Adjust it for Calibre 5.14.0.
