fix(map.jinja): use pillar/config .get according to __cli option

* Fix 5dc0b86 in saltstack-formulas#95
  - No option `merge=True` for `config.get`
* Use `pillar.get` for `salt-call` (i.e. `salt-ssh`)
  - Differentiate `salt-ssh`/`salt-call` via. `root_dir`
* Use `config.get` via. `defaults.merge` otherwise
  - Reintroduce based on 775a930 in saltstack-formulas#20
