[PATCH] base: Fixup PACKAGECONFIG incorrect mappings

[Richard Purdie <richard.purdie@linuxfoundation.org>]

PACKAGECONFIG doesn't work in cross-canadian recipes at the moment as
DEPENDS are prepended with mlprefix.

A recipe is either nativesdk, native or target so adjust the if
statements accordingly, use inherits_class for more accurate recipe
classification and add cross-canadian support.
