cpu_map: Add cpu feature avx-vnni

Browse Source 
"avx-vvni" was introduced to qemu in commit
c1826ea6a052084f2e6a0bae9dd5932a727df039, adding it Cooperlake.

This feature is currently not used by any libvirt CPU models, but its
addition silences a warning from sync_qemu_i386.py:

```
warning: Unknown feature 'CPUID_7_1_EAX_AVX_VNNI'
warning: Feature unknown to libvirt: CPUID_7_1_EAX_AVX_VNNI
```
