You can't.  At least not directly.  Lua's written in ANSI C, and
therefor does not have a setenv() to go along with getenv()/main()'s
third parameter.

You can either bind your OS's setenv-like/spawn-like API calls yourself,
or do the evil thing and generate a shell script/batch file that does
the right thing, and then run that.
