Fix proxy and module_hotfixes (#6837)

This fixes the Containerd + EL8 case that was missed in 7d1ab337

On CentOS 8 with proxy ansible render inline `proxy` and `module_hotfixes` options.

For example:
```
proxy=http://127.0.0.1:3128module_hotfixes=True
```

But expected result:
```
proxy=http://127.0.0.1:3128


module_hotfixes=True
```
