bitbake: cooker.py: remove generation of recipe-depends.dot

The information of recipe-depends.dot is misleading.

e.g.
$ grep xz recipe-depends.dot | grep bzip2
"bzip2" -> "xz"
"xz" -> "bzip2"

Users would wonder why they get some circular dependency.

The information is derived from removing the task names
of task-depends.dot. It's not giving people any additonal
information, and it's misleading.

So we remove the generation of this file.
