bdrewery asked me for a complete-ish patch so that he could test it
(exp-run?), so I'll work on that.

I made the following changes:
- rename kernsrc to kmod to better reflect that it is about kernel
modules, not just about the kernel source
- added the :C,^/,, modifier to PLIST_SUB so that the leading '/' in
%%KMODDIR%% gets stripped (more compatible with other ports I
think...)

Thanks,
René
