Generate jsongen.py and maskaudit.py from templates...
...so that @PYTHON@ can be substituted with the discovered path to python. Avoids the nonportable assumption that "/usr/bin/env python" will find python, because on pkgsrc systems python2.5 etc. are installed with no bare python to avoid programs binding to a version (and hence compiled extensions) that might change. This should cause no functional change on systems with 'python', and fix the build on pkgsrc-using systems.
