This patch  an attribute  of application_exec_type to any executable 
that can be executed by a user. 

I have only patched the executables that currently transition to a 
domain if run under inetd or init, but do not transition if run by a user.

Also changed corecommand_exec_any to only execute executables that a 
user is supposed to run.  So if sysadm_t tries to execute a dameon 
directly it will get a permission denied.
