Comment # 5 on bug 1182849 from Neal Gompa

I'm not sure if I can write YaST code to fix this, but we'd probably need
equivalents for patching /etc/dnf/dnf.conf for this new setup.

Purely riffing off what I saw for the openSUSE MicroOS kiwi configs, this is
what I did for the PK-DNF based one:

```
#======================================
# Disable recommends
#--------------------------------------
echo "install_weak_deps=False" >> /etc/dnf/dnf.conf

#======================================
# Disable installing documentation
#--------------------------------------
echo "tsflags=nodocs" >> /etc/dnf/dnf.conf
```
