linux-dummy: add empty dependent packages

some kernel includes kernel-image-image and kernel-devicetree packages.
these patckages are defined in kernel.bbclass
but, when use linux-dummy, these packages are not defined.
so, define them as empty packages for avoiding compile error:

ERROR: Nothing RPROVIDES 'kernel-devicetree'
