lxc_container fails when executing the lxc command (e.g. when creating
a new container) because PR#5358 broke the module argument
parsing. The resulting argument dict contained only the module argument name
and the argument flag but not the value. E.g.
```
- lxc_container:
template: debian
```
would result in lxc command arguments `lxc template --template` instead of
`lxc --template debian`.
Fixes: 6f88426cf1 ("lxc_container: minor refactor (#5358)")
Fixes#5578
