capabilities: do not special case exec of init
When the global init task is exec'd we have special case logic to make sure the pE is not reduced. There is no reason for this. If init wants to drop it's pE is should be allowed to do so. Remove this special logic. Signed-off-by: Eric Paris <eparis@redhat.com> Acked-by: Serge Hallyn <serge@hallyn.com> Acked-by: David Howells <dhowells@redhat.com> Acked-by: Andrew G.
