[OE-core] [PATCH 2/7] nativesdk-buildtools-perl-dummy: fix rebuilding when SDKMACHINE changes

[Paul Eggleton]

This recipe produces an empty dummy package (in order to satisfy
dependencies on perl so we don't have perl within buildtools-tarball).
Because we were inheriting nativesdk here the recipe was being rebuilt,
but having forced PACKAGE_ARCH to a particular value the packages for
each architecture were stepping on eachother. Since the packages are
empty they can in fact be allarch (even though they won't actually go
into the "all" package feed). It turns out that nheriting nativesdk
wasn't actually necessary either, so drop that.

Fixes [YOCTO #8509].
