katautils: check config template and vsock

Browse Source 
Vsock conflicts with factory, when both of them are enabled,
kata will try to create a new vm template which is useless,
thus it's better to return an error directly to let users know
that those two config cannot be enabled at the same time.

Fixes: #1055
