Switch build system to accompanied kernel headers
This helps reducing our build-time checks for feature support in the available Linux kernel headers. And it helps users that do not have sufficiently recent headers installed on their build machine. Consequently, the patch removes and build-time checks for kvm and vhost in configure, the --kerneldir switch, and KVM_CFLAGS. Kernel headers are supposed to be provided by QEMU only. s390 needs some extra love as it carries redefinitions from kernel headers.
