secilc: expand generated attributes

Attributes added to the policy by the policy compiler are causing
performance issues. Telling the compiler to expand these
auto-generated attributes to their underlying types prevents
preemtion during policy lookup.

With this patch the number of attributes in policy drops from
845 to 475. The number of attributes assigned to the bluetooth domain
drops from 41 to 11.
