Properly reread entry after failure in nss_files getent function (bug 18991)
* nss/nss_files/files-XXX.c (position, need_reread): New
variables.
(CONCAT(_nss_files_set,ENTNAME)): Initialize them.
(CONCAT(_nss_files_get,ENTNAME_r)): Likewise. Reposition stream
if last call was uncessful.

variables.
(_nss_files_setaliasent): Initialize them.
(_nss_files_getaliasent_r): Likewise. Reposition stream if last
