feat(third_party/nixpkgs): allow setting crossSystem

Browse source 
This allows cross-compiling depot targets to other architectures, so
`nix-build --argstr crossSystem aarch64-linux -A tvix.nar-bridge`
will emit a cross-compiled aarch64-linux binary.

There's still some other cross-related issues in crate2nix to sort out
for crate2nix builds, but this CL can already land.
