Subject: [PATCH] nixos/dhparams: mark service `${name}` requires
 `dhparams-gen-${name}`

This can prevent someone delete the generated file in `/var/lib/dhparams/${name}.pem`
and the `${name}.service` will still be happy to start
without starting `dhparams-gen-${name}` to re-generate the deleted file.
