Thomas Lamprecht 376d9ce806 Write recognized CPUID flags into static file
located at /usr/share/kvm/recognized-CPUID-flags-x86_64

It's a simple one flag per line list of all flags the build of QEMU
can understand for x86_64 CPUs.

It will be used in qemu-server for the custom CPU model feature.

For now, only x86_64 is implemented, since aarch64 doesn't print any flags when
called this way.
