cpuset: don't set cpuset.mems in the guest

Browse Source 
Kata doesn't map any numa topologies in the guest. Let's make sure we
clear the Cpuset fields before passing container updates to the
guest.

Note, in the future we may want to have a vCPU to guest CPU mapping and
still include the cpuset.Cpus. Until we have this support, clear this as
well.

Fixes: #932
