nixos/caddy: don't set ExecReload if enableReload is disabled 

Otherwise, setting services.caddy.enableReload to false fails in a very bad fashion:

The reload command still gets executed, but fails:

```

Apr 26 21:23:01 n1-rk1 systemd[1]: Reload failed for Caddy.
```

… and the server is not restarted either, as a ExecReload= command is
specified.

Fix this, by only setting ExecReload if the reload exists.

The first empty string is still necessary to reset the old option.
