global-functions: $MkDir: abuse smb share to create directory

Browse source 
The smb feature is provided by system package... So we have it anyway.
It gives some benefits compared to abusing fetch:

* It is faster!
* No need to alter, enable and restore a service! (The share is created disabled.)
* Firewall rules can not break this.
* No temporary file is created.
* Less code!

Let's hope we do not introduce new breakage.

Closes #14
