Bug#698102: initgroups changes egid on kfreebsd

[Petr Salinger <Petr.Salinger@seznam.cz>]

Hi Michael,

please would you mind to try patch bellow ?

The function internal_getgrouplist() in grp/initgroups.c 
puts supplied "group" as the first entry in all but NSCD cases.

Please could you test whether it fixes the problem in your 
environment.
