Subject: [PATCH] Tests: Teach CMakeOnly.AllFindModules to tolerate a system
 KDE4

The FindKDE4 module (incorrectly) modifies CMAKE_MODULE_PATH on the
caller's behalf.  This causes KDE4-installed find modules to be used by
the test instead of those in CMake.  Teach the test to restore the
CMAKE_MODULE_PATH to its original value after each find_package call.
This ensures that the next find_package actually tests our module.
