Allow setsebool_t relabel selinux data files

Since the "libsemanage: Preserve file context and ownership in policy store"
commit [1], libsemanage ensures that ownership and also SELinux context
of policy data files are correct.

This requires additional permissions for setsebool_t when there is
a process transition for the setsebool command defined, such as when
executed from an rpm scriptlet.

Assigning to the following attributes is also needed:
- can_change_object_identity because it actually is the user part of the
  context which is being fixed; role part is not a subject of constraint
  violation rules
- can_relabelto_binary_policy to be able to modify the policy store context
  (neverallow rule)
