Untrack legacy trees and purely legacy docs (kept locally)

- patches/ -> legacy-patches/ (gitignored)
- legacy-driver-guest/ (old guest vGPU driver, gitignored)
- docs/old/ (superseded architecture write-up, gitignored)
- docs that only reference the legacy components stay tracked; their path
  references now point at legacy-patches/
- install.sh PATCH_DIR updated
