Ettore Di Giacinto e370318bd7 fix(vllm): seed pybind11 for fastsafetensors build under --no-build-isolation
fastsafetensors==0.3 (transitive dep of vllm) imports pybind11 in
setup.py without declaring it in build-system.requires. With
--no-build-isolation it has to already exist in the venv, otherwise the
wheel build fails with ModuleNotFoundError on arm64 L4T CUDA 13 (and
any other profile that picks up vllm 0.20.0).

# mabma does not specify it's build dependencies per PEP517, so we need to disable build isolation
# this also means that we need to install the basic build dependencies into the venv ourselves

# pybind11 is needed to build fastsafetensors==0.3 (transitive dep of vllm) — its
# setup.py imports pybind11 unconditionally but doesn't declare it in
# build-system.requires, so under --no-build-isolation we have to seed it ourselves.
