mission-center: add GPU drivers to LD_LIBRARY_PATH

This fixes an issue where NVIDIA cards will not show up on NixOS.

Under the hood, missioncenter-magpie executable uses nvtop to read
information for and stats about GPU devices. nvtop uses `dlopen` to
load vendor-specific libraries at runtime. For NVIDIA cards, this
requires having the appropriate version of `libnvidia-ml.so` available
under the LD_LIBRARY_PATH or RUNPATH.

Ideally, we would use `addDriverRunpath` directly to edit the
`missioncenter-magpie` RUNPATH. We instead have to wrap it with an
updated LD_LIBRARY_PATH to include the path which `addDriverRunpath`
would have added, as `$out/bin/missioncenter-magpie` is actually an
executable wrapper created by the `wrapGAppsHook4` hook.
