target-i386: Set migratable=yes by default on "host" CPU mooel
Having only migratable flags reported by default on the "host" CPU model is safer for the following reasons: * Existing users may expect "-cpu host" to be migration-safe, if they take care of always using compatible host CPUs, host kernels, and QEMU versions. * Users who don't care aboug migration and want to enable all features supported by the host kernel can simply change their setup to use migratable=no. Without this change, people using "-cpu host" will stop being able to migrate, because now "invtsc" is getting enabled by default. We are not setting migratable=yes by default on all X86CPU subclasses, because users should be able to get non-migratable features enabled if they ask for them explicitly.
