qemu: do not define known no-op features
Qemu dropped cpu features for osxsave and ospke [1][2].
The reason for the instant removal is that those features were never
configurable as discussed in [3].

Fortunately the use cases adding those flags in the past are rare, but
they exist. One that I identified are e.g. older virt-install when used
with --cpu=host-model and there always could be the case of a user
adding it to the guest xml.

This triggers an issue like:
  qemu-system-x86_64: can't apply global Broadwell-noTSX-x86_64-
  cpu.osxsave=on: Property '.osxsave' not found

Ensure that this does no more break spawning newer qemu versions by
not rendering those features into the qemu command line.
