[PATCH 1/9] pylibfdt: We don't need include files from the base directory

[David Gibson <david@xxxxxxxxxxxxxxxxxxxxx>]

pylibfdt/setup.py currently adds include flags to the extension module
build to allow include files in the base dtc directory.  But pylibfdt
doesn't rely on any headers there, only on headers in libfdt/ - it also
shouldn't rely on dtc headers at any future time.

So, remove that from the include list, allowing some simplifications to
setup.py.
