include/assert.h: Use mock_assert() for ENV_TEST targets

Browse Source 
Some tests have to be able to catch assertion errors.
Adding CMocka mock_assert() enables that.

Additionally fix test_imd_create_tiered_empty(),
test_full_stack() and test_incorrectly_initialized_stack()
by adding missing expect_assert_failure().
