[refpolicy] [PATCH v1.0.2] add policy for Icecream

Hello,

This patch adds the policy for Icecream, a distributed compiler.

Notable changes since the first version:
 - as suggested by Dominick Grift:
   - reordered lots of the lines
   - removed the comments
   - dontaudit siginh, rlimitinh, noatsecure
   - use application_domain() for iceccd_createenv_t
   - use can_exec()
I did not add any interfaces, I like it better without them.

Michal
