Remove timeout wrapper from nft command

Run sudo nft directly without timeout wrapper to preserve capabilities.
The timeout -> sudo chain was preventing nft from accessing netlink
with proper permissions.

- Change from 'timeout 3 sudo nft' to 'sudo nft'
- Allows CAP_NET_ADMIN to pass through correctly
- Update version to v0.1.256
