If we only want debugging information for vmlinux and not kernel modules, it'd be nice to only load the former. This adds a load_main parameter to drgn_program_load_debug_info() which specifies just that. For now, it's only implemented for the Linux kernel. While we're here, let's make the paths parameter optional for the Python bindings.
