Subject: [PATCH 5/9] pylibfdt: Make SETUP make variable

This points to the Python setup script, since we reference it in a couple
of places.  While we're there correct two small problems:

1) setup.py is part of the checked in sources and so lives in
   $(PYLIBFDT_srcdir) not $(PYLIBFDT_objdir) [this only worked because
   those are the same by default]

2) The module itself should depend on the setup script so it is rebuilt
   if the script is changed
