update-linux-headers.sh: Don't hard code list of architectures
Rather than hardcoding the list of architectures in the kernel header update script, just import headers for every architecture which supports KVM (with a blacklist exception for ia64 which has KVM headers but is dead). This reduces the number of QEMU files which need to be updated to add support for a new KVM architecture.
