pylibfdt: Use setuptools_scm for the version

Browse source 
The DTC version in version_gen.h causes a warning with setuptools:

setuptools/dist.py:501: UserWarning: The version specified ('1.6.1-g5454474d') \
is an invalid version, this may not work as expected with newer versions of \
setuptools, pip, and PyPI. Please see PEP 440 for more details.

It also creates an unnecessary dependency on the rest of the build
system(s). Switch to use setuptools_scm instead to get the version for
pylibfdt.
