scripts/bitbake: add a version >= 2.6 check

Unfortunately we now have code in BitBake which is parsed before the
current version check and is incompatible with Python < 2.6. Rather than
fixing this and being eternally vigilant for >= 2.6 feature usage, just
add a version check to the wrapper script.
