[Buildroot] [PATCH v2] uboot-tools: disable pylibfdt

[Matt Weber]

1) Removed the host system swig check which is proposed
for being fixed upstream in 2017.11 by making pylibfdt
selectable via KCONFIG.

2) Removing the swig/python setup.py prevents the Python.h
error also causing build failures.  That bug was resolved in
2017.9.
