Silence meta-virtualization warning message

Starting with Rocko the meta-virtualization layer will emit a
warning about missing virtualization in DISTRO_FEATURES.

Silence the warning rather than adding the feature as true
virtualization support is not required on OpenBMC at the
moment.

Tested: Built witherspoon and palmetto images with Rocko
