Fix Arch/Manjaro install script to include all required dependencies

- Add base-devel and pkgconf packages for Go CGO compilation
- Add xorriso package for DVD ISO extraction (was missing)
- Add --needed flag to avoid reinstalling existing packages
- Add graphics driver detection with helpful warnings for NVIDIA/AMD GPUs
- Non-invasive: warns about missing drivers but doesn't auto-install them
