That is a much less invasive change than my previously suggested (but
for some reason a bit flawed) approach [1]. Thanks!

This imposes a deterministic ordering, making diffs more predictable
and allowing reproducible testing.

        * src/abg-tools-utils.cc (get_binary_paths_from_kernel_dist):
        Sort module_paths.

Hello Giuliano,
