Although the relocate_sdk.sh supports python3, fc23 does not symlink
/usr/bin/python3 to /usr/bin/python. Using exec instead of a call to
the correct interpreter causes a failure on fc23 when python2 is not
present. This uses 'which' to locate python, python2, then python3 and
uses the first one that's found.
