[PyQt] pyqt-bundle without Qt Network Auth

[Florian Bruhin]

Hey,

Thanks so much for pyqt-bundle - it makes my life a lot easier to be able to
test new Qt Alpha/Betas without having to recompile PyQt!

One thing I noticed is that it crashes when the optional Qt Network Auth module
isn't installed. If I only install Qt and the WebEngine addon (but not Qt
Network Auth) via the Qt installer, then try to run it, I get:

    $ pyqt-bundle PyQt5-5.14.1-5.14.1-cp35.cp36.cp37.cp38-abi3-manylinux2014_x86_64.whl --qt-dir ~/code/qt/bin/5.15.0/gcc_64/
    [...]
    PyQt5/QtNetworkAuth.abi3.so: RPATH=$ORIGIN/Qt/lib
    PyQt5/QtNetworkAuth.abi3.so: new RPATH: $ORIGIN/Qt/lib
    pyqt-bundle: An internal error occurred...
    Traceback (most recent call last):

      File "/usr/lib/python3.8/shutil.py", line 426, in copy2

        with open(src, 'rb') as fsrc, open(dst, 'wb') as fdst:
    FileNotFoundError: [Errno 2] No such file or directory: '/home/florian/code/qt/bin/5.15.0/gcc_64/lib/libQt5NetworkAuth.so.5'

I'm not sure what should happen in that case, though. I think it should be
possible for pyqt-bundle to just not bundle that .so (even though PyQt
originally was compiled against it), and the wheel would work fine in general?
Then when trying to import QtNetworkAuth I suppose one would just get a
slightly more cryptic ImportError rather than a ModuleNotFoundError.
