selkies: GPU-accelerate 32-bit GW via mounted 32-bit nvidia GL + vglrun launcher

Browse source 
Mount config.hardware.nvidia.package.lib32 into the container (CDI only carries
64-bit driver libs) and add a `gw` launcher that runs Guild Wars through
VirtualGL on the M2000. Drops GW from ~18 software-rendered CPU cores to <1.
Also bump stream to 60fps.

# `gw` launcher: GW is 32-bit, so it needs the 32-bit NVIDIA GL libs (mounted
# at /usr/lib/i386-linux-gnu/nvidia by the service) on the loader path, and
# VirtualGL (EGL backend) to render on the M2000. Without this GW falls back
# to llvmpipe (software) and pegs ~18 CPU cores at <20 fps.
