misc/llama.cpp: update to b6934 with required update devel/libggml

ports@,

I'd like to update our misc/llama.cpp to the last snapshot (b6934).

It allows to run https://huggingface.co/collections/Qwen/qwen3-vl models.

We don't have GPU but with -t 32 I had run Qwen3 VL 30B model on CPU only at
AMD Ryzen 9 7950X3D with acceptable to use speed like 2 tokens/second which
more or leass useble. But it requires memory. 120G as :datasize is enough.

Because we uses libggml as dedicated port, it must to be updated to the last
version, and it contains a bug which brokes large models under large number
of threads: https://github.com/ggml-org/llama.cpp/issues/16960

I had included a patch to fix this issue as well.

I had tested analyze of .pdf document, chat and "explain the picture" on
-current/amd64. Everything works.

Ok?
