sysusers: always treat ENOENT as entry-not-found when doing NSS calls
For most NSS calls it is documented that they return NULL + errno=0 when an entry is not found. However, in reality it appears to be common to return NULL + errno=ENOENT, instead. Handle that correctly, and don't consider ENOENT a systematic error.
