[OE-core] [PATCH] native: remove PN from DEPENDS automatically

[Ross Burton]

If a recipe (say, wayland) has DEPENDS=wayland-native and BBCLASSEXTEND=native,
when built as wayland-native it has DEPENDS=wayland-native which results in a
circular dependency.

Typically this is resolved by having explicit DEPENDS_class-native statements
but as this is duplication which can lead to inconsistent dependencies,
automatically remove the circular dependency.
