Change kore_parent_configure() for single binaries.

This function now takes any remaining arguments passed on the command line
after kore parsed its own.

For C the new prototype looks like this:

void kore_parent_configure(int argc, char **argv);

For python code, kore will pass each argument to the function so you
can do things like:

def kore_parent_configure(arg1, arg2):
