ggml-cpu : disable tiled matmul on AIX to fix page boundary segfault (llama/22293)

* ggml-cpu : disable tiled matmul on AIX to fix page boundary segfault

vec_xst operations in the tiled path crash on AIX when writing
near 4KB page boundaries due to strict memory protection. Fall
back to mnpack implementation on AIX for stable execution.
