Add privilege-Smack mapping

Add privilege-Smack mapping

Add privilege-Smack mapping configuration:
* privilege-smack.list which describes privilege mapping
  to Smack label and Smack rules template
* priv-rules-default-template.smack which is an example
  of Smack rules template for privilege
* this implementation currently only applies policy on
  application launch (no runtime policy changes modify it)
and draft implementation.

IMPORTANT: This mechanism can be used, when *only one* user
           is used on Tizen.
