JobService: add "directory creation" job

Adds a "mkdir" job in masquerade (which can be called by substratum).
It allows creating folders in directories otherwise unaccessible without root
(but it still has its limitations, because it uses the "system" user).

It also allows creating the "data/system/theme" folder as a fallback for
when the platform/core commit fails.

A combined work with @KreAch3R
