[PATCH] implement module_arch_cleanup() in all architectures

From: Rusty Russell <rusty@rustcorp.com.au>, David Mosberger

The patch below updates the other platforms with module_arch_cleanup().
Also, I added more debug output to kernel/module.c since I found it useful
to be able to see the final section layout.
