coreutils: Improve core-utils-native dependency handling

bash-dev-native does not exist, nor should it. Tweak the recipe so that if/as/when
we fix native ${PN}-XXX handling, this doesn't break. Use variable indirection
as the least worse solution as an override directly will get overwritten with
variable renaming, resulting in a warning.
