Something has corrupted your local kernel header installation. Do(did) 
you have other -dkms packages installed?

You could check the status of your packages with
   dpkg --verify

If you reinstall the affected package(s), the missing/broken files will 
be repaired and the module should build afterwards.

apt-get install --reinstall <pkg>...

PS: If you can find the source of this corruption (which is likely to 
reappear in the future), we would be really thankful. This is not the 
first time it happened ...
