pylibfdt: allow build out of tree

Browse source 
With meson, we have to support out-of-tree build.

Introduce a --top-builddir option, which will default to the current
directory to lookup generated filed such as version_gen.h and output
directories.

Other source paths are derived from the location of the setup.py script
in the source tree.

--build-lib is changed to be relative to the current directory, instead
of relative to setup.py. This has less surprising results!
