relocate_sdk.py: allow relocate_sdk.py to work with python 2.4.x

Avoid the chicken / egg problem of an SDK that provides a working
python but requires that version of python to extract itself.  The
RHEL 5.x systems and some other enterprise Linux systems ship with
python 2.4.x as the default python.  We need to at least be able to
extract work executables even if we never use the the host provided
python again.
