python: Fix cgi.py runtime issue

By default cgi.py attempts to use /usr/local/bin/python as its
interpreter.  However, on my Linux systems, including OE-Core,
python is installed into {bindir}.  Adjust this one file based on
the comment at the top of the upstream file.

This resolves an issue where a runtime dependency discovered during
RPM packaging breaks the rootfs construction.

(From OE-Core rev: 1da01664963b9c6a6df171dcd0fbb1406544035b)
