Upgrade llama.cpp from b9219 to b9222 (#169)

No source changes required. The b9219..b9222 diff is limited to:
- Hexagon HTP backend: additive GGML_OP_PAD and GGML_OP_TRI support
  (new pad-ops.c, HVX-vectorised tri_f32; internal Qualcomm DSP only)
- Dockerfile/CI: OCI image labels, skip_s390x workflow input

All 417 C++ tests pass.
