For --embed mode, always initialize the global variable
__pyx_module_is_main_MODULE to zero, even with --embed, and only set it
to one in main().  This would allow the same code to still work if
compiled as a shared library (main would be ignored) and also make the
code cleaner since all of the --embed stuff would be in one place.
