kernel-yocto.bbclass: move do_kernel_link_vmlinux() into kernel.bbclass

Move do_kernel_link_vmlinux() from kernel-yocto.bbclass into
kernel.bbclass so that it's available to any kernel recipe.

Note that the task is not enabled by default in kernel-yocto.bbclass,
so don't enable by default in kernel.bbclass either. To enable, see
the example in linux-yocto.inc, ie:

  addtask kernel_link_vmlinux after do_compile before do_install
