Subject: [PATCH] testing: fix finding tests on new cmake versions

By chance, cmake was installed by homebrew without any restrictions,
and so version 4.0.2 happened to be installed which does no longer
use the option "--force-new-ctest-process". Changed the analysis to
look for "/bin/ctest" instead. This should work for a long time.

Task-number: PYSIDE-2221
Change-Id: Idc16063953ba82d4053cc60a7e0ef11b71b7b571
Pick-to: 6.9
