To answer my own question:

Yes Tkinter is included in Python build but as the patch states it needs 
tcl as well as tk with tcl already included in Yocto and tk not.

Andrei Gherzan wrote a .bb for OE-Core for tk version 8.5.11 which did 
work for me after bumping it to the latest version 8.6.1.

If anybody needs it or wants to integrate it in Yocto here is the bb: 
(just remember to include tk and tcl in your build or add dependencies 
for them in python).
