[PATCH] cooker: Fix incorrect dot file generation

[Richard Purdie <richard.purdie@linuxfoundation.org>]

In the runqueue cleanup/conversion, "dep" was mistakenly used where "tid" should
be leading to incorrect task-depends.dot files and causing general confusion. 
Fix this, its clearly incorrect looking at the code.
