rb: add verify exclusion for RB-replaced upstream functions

52 functions documented as intentional RB replacements across:
- initfs (8): RB uses different initfs tooling
- driver-graphics KMS (16): RB refactored display layer
- ihdgd Intel GPU (5): RB driver refactoring
- vesad (2): RB framebuffer refactoring
- virtio-gpu (12): RB async GPU refactoring
- inputd/input/net (3): RB daemon pattern refactoring
- pcid (2): RB PCI refactoring
- xhcid USB (4): RB USB refactoring
- redoxerd (1): RB executor refactoring
- netstack (1): RB network refactoring
- ramfs (2): RB filesystem refactoring
