Log Message:
Don't set P_SUGID if the calls to set{e,}{u,g}id(), setreuid(),
setgroups() did not result in actual changes. This has the nice
side effect that we don't needlesly allocate new credential and
resource limit data structures.

This is so that non setuid programs that call seteuid(getuid()),
don't end up setting P_SUGID, resulting in broken behavior [i.e.
non setuid ssh, doesn't read ~/.hostaliases...].

This is a good candidate for a pullup, if someone reviews it.
