git-cola needs pyside to start but does not depend on it

Running Ubuntu 20.04 under Windows 10 WSL I still get the "PySide" problem even though PyQt5 is installed as a dependency of git-cola by apt install. The problem is that libQt5Core.so.5 fails to load because it calls a kernel function that doesn't exist in the distribution I'm using. The fix is to run "sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5".

See https://askubuntu.com/a/1163268/358938 for the discussion that led me to this fix.

I know this isn't git-cola's fault, but hopefully others will find this solution when they search for the same symptom as me.
