[WireGuard] new build process doesn't work with debian's dkms

hi there--

i'm trying to package wireguard experimental-0.0.20160722 for debian, and it looks
like the new Kconfig/Kbuild/Makefile revamp from
3106d632de4235f8c6d63d602fe2fa9e0175d690 causes the version of dkms to
not be able to build it automagically.

In particular:

----------
0 root@sid:~# dkms build wireguard/0.0.20160722

Kernel preparation unnecessary for this kernel.  Skipping...

I probably need to grok the new build system a bit more when i have some
time, but if anyone has any pointers for integrating it with dkms, i'd
be happy to hear what you thought was necessary.

just wanted to report why this isn't already uploaded to debian yet.

     --dkg

uh, please chalk this up to lack of sleep and general delirium, it's all
working fine when i remember to actually ship Kconfig and Kbuild :)

Glad to hear. I figured it was something like that :P.
