fix(installer): Disable metacopy for cri-o

Summary:
metacopy breaks cri-o ubuntu 18.04 with the current releases. I'm not really sure what's wrong there but it's not possible to even create a pod with this setting enabled and current releases of cri-o.

The following github issues describe the issue:
cri-o/cri-o#5104
cri-o/cri-o#4574
