* [Barefoot] Update bfn sde url for 8.5.0

* Update bfn-platform.mk

Includes changes:

- Fix pre shutdown select (sonic-net/sonic-sairedis#397)
- [.gitignore]: Add more files in .gitignore file (sonic-net/sonic-sairedis#396)
- Add check ASIC vs DB state after comparison logic (sonic-net/sonic-sairedis#393)
- Process only shutdown requests after pre shutdown (sonic-net/sonic-sairedis#395)

knet driver unload takes about 30 seconds to remove netdevs. This cuts
into our warm reboot time budget.
