installkernel - Fix kernel.old/kernel overwrite

* The kernel was being copied to kernel.old/kernel twice, once normally,
  and once (after the new kernel was installed) by the module objcopy.

  This left kernel.old/kernel as the new kernel instead of the old kernel.

* Fix by restricting the module copy to .ko files.
