Test limactl copy

[nirs]

The copy command seems to be tests only in one case, copying file from vm to host. The command support many other untested operations.

Tests:

• copy single file from vm to host

  • lima/hack/test-templates.sh

    Line 197 in e911564

    limactl cp "$NAME":/etc/hostname "$tmpfile"

• copy single file from host to vm
• copy directory from vm to host
• copy single file from vm to host
• copy directory from vm to host with --recursive flag
• copy directory from host to vm with --recursive flag
• copy multiple sources from vm to host
• copy multiple sources from host to vm
• copy multiple sources from vm to host with --recursive flag
• copy multiple sources from host to vm with --recursive flag

I'm not sure that adding these test-template.sh is the best way, it is very hard to work with such a big test.

I think we need to use go test running limactl with test vms created before the test.
