python-scons*: upgrade to 3.0.0

Both python-scons and python-scons-native need to be upgraded to latest
upstream version.
LIC_FILES_CHKSUM changed due to updated year in date, but rest of file
remain the same.
Following dependencies were added to enable appropriate package usage:
python-shell, python-pprint and python-importlib.
A patch was taken from upstream to support python2 print statements
in SConscripts. This should be included in next version.
These changes were tested in qemux86 with core-image-minimal.
