fix erroneous return of partial username matches by getspnam[_r]
when using /etc/shadow (rather than tcb) as its backend, getspnam_r matched any username starting with the caller-provided string rather than requiring an exact match. in practice this seems to have affected only systems where one valid username is a prefix for another valid username, and where the longer username appears first in the shadow file.
