If the samples don't link with libvulkan directly, it won't get pulled=
into the images. How are they loading that library, is it via dlopen()
somewhere? Invisible dlopen() dependencies typically need to be listed
explicitly in RDEPENDS.

As a quick fix, you can add vulkan-loader to the same
CORE_IMAGE_EXTRA_INSTALL list.
