Tests: Avoid interference from environment in RunCMake.find_library
Clear $ENV{CMAKE_PREFIX_PATH} in several RunCMake.find_library tests because on Windows, a CMAKE_PREFIX_PATH with two consecutive semicolons causes a library to be found when it should not be.
None of the updated tests expect CMAKE_PREFIX_PATH from the environment to influence the test, so clear the variable entirely to guarantee it will not affect the test.
