When adding `nixpkgs` as flake-input using the `path`-fetcher, you
currently get the following error since neither `lastModifiedDate` nor
`lastModified` are stored in `flake.lock` for paths:
```
error: --- EvalError --------------------------------------------------------------------------- nix-build
at: (48:71) in file: /nix/store/147clg8svaxyj7pl80ra9kmmm72mdg94-source/flake.nix
47| system.nixos.versionSuffix =
48| ".${final.substring 0 8 (self.lastModifiedDate or self.lastModified)}.${self.shortRev or "dirty"}";
| ^
49| system.nixos.revision = final.mkIf (self ? rev) self.rev;
attribute 'lastModified' missing
```
This patch adds the fallback-value `19700101` to `versionSuffix` if none
of `lastModified{,Date}` are set in the lockfile.
