Previously, it would recognize it as a valid shell only
if the basename (nologin) was specified. Now, it will
recognize both the basename and the full path.
NOTE: The full path as adduser(8) understands it is /usr/sbin/nologin.
There is a symlink, /sbin/nologin, but that's deprecated and
only there for backwards compatibility.
