Ubuntu 26.04 ships with Python 3.14 as the default, but torch~=2.6.0 (required by requirements-convert_hf_to_gguf.txt) has no wheel for Python 3.14. This causes the 'full' stage pip install to fail with: ERROR: No matching distribution found for torch~=2.6.0 Fix: explicitly install python3.13 + python3.13-dev and register it as the default python3 via update-alternatives, matching the fix applied upstream in ggml-org/llama.cpp@fc350fdf (ggml-org#20530).

Two Dockerfile fixes:
1. vulkan.Dockerfile: replace apt-based python3.13/python3.13-dev
install with uv (Astral Python manager). Ubuntu 26.04 ('resolute')
does not ship python3.13-dev as a separate apt package, causing the
'full' stage to fail with exit code 100 ('Unable to locate package
python3.13-dev'). Using uv to install Python 3.13 independently of
the system package manager resolves this.
Also switches build-stage SSL dep from libcurl4-openssl-dev to
libssl-dev, consistent with upstream refactor (ggml-org#18828).
2. s390x.Dockerfile: replace libcurl4-openssl-dev with libssl-dev in
the build stage, matching upstream refactor (ggml-org#18828).
Fixes: vulkan linux/amd64 'full' stage failing with exit code 100
Refs: ggml-org#20530, ggml-org#18828
