populate_sdk_ext: don't remove the native qemu dependencies

These dependencies were deliberately removed because it was assumed that
they were provided by nativesdk packages. On the one hand, nativesdk packages
in extensible SDK don't have these packages; on the other hand, even if we
add these nativesdk packages, they are still not useful because we we need
runqemu to run correctly.

So we don't remove these native qemu dependencies.
