Support python 2 print statements in SConscripts

This fixes a regression introduced in scons-3.0.0, where
SConscripts containing python 2 print statements would cause
syntax errors even when executing scons with python 2.7.

This ensures backward compatibility, allowing users to build
legacy code with scons-3.0.0 without having to patch it.
