Joachim Hummel 500a939db4 Fix DKMS build using the wrong kernel version ...

The DKMS Makefile built against /lib/modules/$(uname -r), the *running*
kernel. When DKMS rebuilds the module for a newly installed kernel (the
common case after an apt upgrade, while the old kernel is still running),
it produced a .ko with the old kernel's vermagic and installed it into
the new kernel's tree. The module then failed to load with "disagrees
about version of symbol module_layout".

Make the Makefile honour a KVERSION variable (defaulting to the running
kernel for manual builds) and have dkms.conf pass DKMS's target kernel
via KVERSION=${kernelver}, so the module is always built for the kernel
it is being installed for.
