bitbake: taskdata: Don't add dependencies on tasks that don't exist

"bitbake meta-toolchain" with qemu image testing enabled causes problems
since it adds a task after do_rootfs which doesn't exist in this case.

We should simply ignore these extra dependencies rather than adding
them in which is what this patch does (adding a debug message when this
happens).
