[PATCH 1/2] qemu-kvm: Use kvm-kmod headers if available

[Jan Kiszka <jan.kiszka@web.de>]

Since kvm-kmod-2.6.32.2 we have an alternative source for recent KVM
kernel headers. Use it when available and not overruled by --kerneldir.
If there is no kvm-kmod and no --kerneldir, we continue to fall back to
the qemu-kvm's kernel headers.
