[OE-core] [PATCH] bin_package: fail if ${S} doesn't actually contain anything

[Ross Burton]

If the user is trying to use bin_package but the SRC_URI hasn't extracted
anything into ${S}, which is easily done when writing a recipe by hand, instead
of silently shippping an empty package abort the build.
