Christian S.J. Peron 60088fb7b1 Currently, if the secure level is low enough, system flags can
be manipulated by prison root. In 4.x prison root can not manipulate
system flags, regardless of the security level. This behavior
should remain consistent to avoid any surprises which could lead
to security problems for system administrators which give out
privileged access to jails.

This commit changes suser_cred's flag argument from SUSER_ALLOWJAIL
to 0. This will prevent prison root from being able to manipulate
system flags on files.

This may be a MFC candidate for RELENG_5.
