fix spurious errors from pwd/grp functions when nscd backend is absent
for several pwd/grp functions, the only way the caller can distinguish between a successful negative result ("no such user/group") and an internal error is by clearing errno before the call and checking errno afterwards. the nscd backend support code correctly simulated a not-found response on systems where such a backend is not running, but failed to restore errno. this commit also fixed an outdated/incorrect comment.
