ENH: Strengthen FindPackageTest version check

The previous change to test finding in lib/cmake/<name>* weakened the
versioned find tests.  Since the lib/cmake paths are searched before
lib/<name>* paths the previous change skipped requiring the command to
ignore zot-3.0 when finding zot-3.1.  This change restores that and adds
zot-4.0 to test the lib/cmake path.
