kbuild: Let kernel-doc.py use PYTHON3 override
It is possible to force a specific version of python to be used when
building the kernel by passing PYTHON3= on the make command line.
However kernel-doc.py is currently called with python3 hard-coded and
thus ignores this setting.

Use $(PYTHON3) to run $(KERNELDOC) so that the desired version of
python is used.
