Tests: Bump CMake minimum required in tests to 2.8.12

Since 3.19, CMake generates a deprecation warning when using a minimum
version less than 2.8.12.  This eliminates those warnings generated
during tests, which are typically hidden from the user and developer but
are being generated nonetheless.
