Write udev rules correctly when renaming multiple devices

bnc#894089h
as an example ... Udev rule is represented this way:
```
default_rule = [
        "SUBSYSTEM==\"net\"",
        "ACTION==\"add\"",
        "DRIVERS==\"?*\"",
        Builtins.sformat("ATTR{address}==\"%1\"", dev_mac),
        "ATTR{type}==\"1\"",
        Builtins.sformat("NAME=\"%1\"", dev_name)
      ]
```
