When playing with the generation scripts for OpenWrt development, I noticed
that these scripts still required Python 2. Future-proof them by replacing
deprecated functions with new Python 3 compatible variants. The result
works with both Python 2.7 and Python 3.x; older Python 2.x releases are
not supported anymore.
regulatory.db and regulatory.bin are unchanged and reproducible across
Python versions. Note that there is no stable release of m2crypto for
Python 3 yet; I used the current development branch for testing.

v2: explicitly open input file with UTF-8 encoding; otherwise the scripts
will fail without a UTF-8 locale set in the environment
