The wheels use the binaries built by Qt, and this is a Qt regression:
https://bugreports.qt.io/browse/QTBUG-88688

Qt doesn't actually require .1, so you might get around this by
symlinking /usr/lib/x86_64-linux-gnu/libxcb-util.so.0 into the installed
wheel's lib directory as libxcb-util.so.1 as a workaround.

I might be able to show some code once I get around to implementing that
workaround myself, probably tomorrow or Thursday.
