Revert "Port to Qt 6's absence of QProcess::setupChildProcess"

This reverts commit 6a66ced594ad0063b088bf743be7ff962bbb5616.

The patch that will introduce the alternative to setupChildProcess
(QProcess::setChildProcessModifier()) has not yet found its
way to qtbase and current Qt dev already identifies itself as
version 6.0.0, rendering the code here uncompilable.
