meta-agl-bsp: update meta-virtualization bbappends

Rename the meta-virtualization dynamically applied bbappends to
handle the newer versions in YP 5.0 / scarthgap.  To some degree
these changes are placeholders to facilitate building the IC EG
container demo images, as the configuration for that pulls in
meta-virtualization.  The virtio support related changes the
bbappends apply here need to be reworked to be actually workable
for the KVM demo images and potential downstream users.
