Fix container command quotes in macvtap.yaml.in (#27)

Use double quotes instead of single quotes in:
command: ['cp', '/macvtap-cni', '/host/opt/cni/bin/macvtap']
because we are using single quotes around template variables
and having single quotes in the above command list
blocks us from using simple sed to remove all single quotes
in the entire yaml template.
