    tests: Fix some memory leaks
    
    This is enough to make many of the tests pass under gcc's
    AddressSanitizer. pixbuf-randomly-modified still fails when it cannot
    allocate more memory, and pixbuf-fail fails with memory allocation
    errors unless run with ASAN_OPTIONS=allocator_may_return_null=1.
