s4-auth: allow to pass original_user_name=NULL to auth_session_info_fill_unix()

With this patch the auth_session_info_fill_unix() uses the "unix_name"
from the session_info->unix_info if no original_user_name was specified.

This is used to process a system session info where no original_user_name
is given.
