[bug#44771] [PATCH] gnu: Properly use $QTWEBENGINEPROCESS_PATH

[Sergey Trofimov]

I've noticed that installing supercollider breaks qutebrowser. It happens
because QTWEBENGINEPROCESS_PATH is not a search path, but rather a full path
to a file.  So supercollider puts this var into the user profile and then
qutebrowser's wrapper incorrectly concatenates it with the path coming from
the qtwebengine dependency. Calibre package has the same defect.
