Currently, AFL_NYX_AUX_SIZE doesn't work because AFL++ uses the hardcoded 0x1000 size for nyx_aux_string rather than the actually set size. This causes ASan traces to still be truncated to 4K, no matter what AFL_NYX_AUX_SIZE is set to.

The attached fix was validated to work in our setup and produces the proper traces now.
