    Fix inconsistent passwd compensation in nss/bug17079.c
    
    It used to be common practice to have a statically linked shell for an
    alternative root account, as in:
    
    root:x:0:0:root:/root:/bin/bash
    toor:x:0:0:root recovery account:/root:/sbin/sash
    
    This causes problems with passwd NSS tests because a UID-based lookup
    will only retrieve one of those entries.  The original version of
    nss/bug17079.c detected this, but failed to use this information later
    on.
