sandbox: fix the issue of failed to get the vmm master tid

For kata container, the container's pid is meaning less to
containerd/crio since the container's pid is belonged to VM,
and containerd/crio couldn't use it. Thus we just return any
tid of kata shim or hypervisor. But since the hypervisor had
been stopped before deleting the container, and it wouldn't
get the hypervisor's tid for some supported hypervisor, thus
we'd better to return the kata shim's pid instead of hypervisor's
tid.

Fixes: #9777
