0xc1c4da eb8eedfdb4 Allow flake to be consumed, and nix build .#rln (#340) ...

I had been trying to consume zerokit (specifically rln on x86_64), to
build libwaku (nwaku) and was having issues, this PR at least allows a
build to occur.

```bash
$ nix flake show github:vacp2p/zerokit
error: syntax error, unexpected '=', expecting ';'
       at «github:vacp2p/zerokit/0b00c639a059a2cfde74bcf68fdf75db3b6898a4»/flake.nix:36:25:
           35|
           36|         rln-linux-arm64 = buildRln {
             |                         ^
           37|           target-platform = "aarch64-multiplatform";
```

`Cargo.lock` is required in repo for this to be possible, otherwise:
```bash
$ nix build .#rln --show-trace

The PR allows for a successful build:
```bash
$ ls -R result
result:
target

result/target:
release

result/target/release:
librln.a  librln.d  librln.rlib  librln.so
```
