The semanage application supports a "semanage permissive" feature,
allowing certain domains to be marked for running permissive (rather
than the entire system).
To support this feature, we introduce a semanage_var_lib_t type for the
location where semanage will keep its permissive_<domain>.* files, and
allow semanage_t to work with fifo_files (needed for the command to
work).
