poky/poky-tiny: Explicitly exclude `shadow`

`login` from busybox has explicit heuristics to handle CONFIG_MULTIUSER
unset (i.e. a kernel without non-root users, groups or capabilities),
bringing in the shadow version of `login` causes obscure failures at
runtime ("setgid: Function not implemented"), instead exclude it here so
anyone who includes it (likely accidentally) will at least get a build
time failure.
