nixos/tests/letsencrypt: Hardcode certs and keys
In 0c7c166 I have set allowSubstitutes to false, which avoided the substitution of the certificates. Unfortunately substitution may still happen later when the certificate is merged with the CA bundle. So the merged CA bundle might be substituted from a binary cache but the certificate itself is built locally, which could result in a different certificate in the bundle. So instead of adding just yet another workaround, I've now hardcoded all the certificates and keys in a separate file. This also moves letsencrypt.nix into its own directory so we don't mess up nixos/tests/common too much. This was long overdue and should finally make the dependency graph for the ACME test more deterministic. Signed-off-by: aszlig <[email protected]>
