Revert "libbsd: replace with nbcompat"
This reverts commit 480434f7eeefed7026dbbd11a4a0b1e4bfc1f137. netbsd.compat does not provide include files that are provided by libbsd [1], and it encumbers its transitive dependents with an obligatory include file that setups BSD-compatible C environment [2]. [1] https://github.com/NixOS/nixpkgs/pull/41320#issuecomment-394922277 [2] https://github.com/NixOS/nixpkgs/pull/41320#issuecomment-394928845
