python: regenerate plat-linux2/*.py

* If plat-linux2/DLFCN.py was present, python was broken in our
  image, i.e. it was unable to load many modules. This was due
  to changed RTLD_* constants in dlfcn.h
* Python includes a script, plat-linux2/regen, to regenerate
  the py source codes in this directory.
* Do what plat-linux2/regen would do, but use files from
  STAGING_INCDIR.
