plasma5.plasma-workspace: fix patch

At some point a patch accidentally removed

```
done
break
```
from an if then/while loop in `startkde`.

Which still breaks, but not the way we want...

plasma-workspace-5.16.5/bin/startkde: line 403: syntax error near unexpected token `fi'
plasma-workspace-5.16.5/bin/startkde: line 403: `        fi'
