Refactor GPU and USB passthrough setup in container scripts

Browse Source 
Introduced a unified gpu_inside_setup function in build.func to handle VAAPI and NVIDIA userland installation inside containers. Replaced bracket conditionals with if statements in passthrough.func for improved readability and maintainability, and made minor logic clarifications for privileged container checks.
