[ddc] Pass an empty array when running main

Match the behavior of the ddc module system when running the
applications main method when using the new library bundle format.

This passes an empty JavaScript array to the main method which is
good enough to get the benchmarks that use main method args to run.

The API should be updated in a way that allows you to actually pass
a JavaScript array of Strings when starting the program.
