base: revert oneshot_async service types, fix local fork deps, migrate remote to RedBear-OS

- Revert initfs/rootfs service types from oneshot_async to blocking
  Scheme/Notify/Oneshot to fix init ordering races.
- Add /scheme/pci retry loop in pcid-spawner.
- Bump redox_event to 0.4.8; use local paths for redox-ioctl and redox-rt.
- Regenerate Cargo.lock / bootstrap/Cargo.lock with only local forks.
- Update submodule origin from redbear-os-base.git to RedBear-OS.git
  branch submodule/base per single-repo policy.
