poky-tiny: set poky and poky-tiny in distro overrides

Since meta-yocto uses a generic poky override for FILESEXTRAPATH in busybox, we really should be setting the DISTROOVERRIDES to both poky and poky-tiny.

I would rather think override in busybox is not needed. since defconfig is inside ${BPN}/poky-tiny
if you did not have _prepend qualifier in FILESEXTRAPATHS_prepend_poky := "${THISDIR}/${P}:"
it would work as expected.
