Fix CMAKE_INSTALL_PREFIX when building against installer-provided Qt

Browse Source 
When building a module against an installer-provided Qt,
CMAKE_INSTALL_PREFIX would default to /home/qt/work/install, which is
the install prefix of our packaging machines.

Do not hard-code the install prefix in QtBuildInternalsExtra.cmake but
use the one that is calculated from the location of
QtBuildInternalsExtra.cmake.

Pick-to: 6.1
Fixes: QTBUG-90449
