Teach debuggerd to pass the secondary ring buffer to __scudo_get_error_info().
With this change we can report memory errors involving secondary
allocations. Update the existing crasher tests to also test
UAF/overflow/underflow on allocations with sizes sufficient to trigger
the secondary allocator.
