pylibfdt: Use environment to pass C flags and files

Browse source 
At present setup.py adjusts its command line when running, so that the
C flags and file list can be passed as arguments. Pass them in environment
variables instead, so we can avoid this messiness. It also allows us to
support the 'install' command.
