vsock/tests: panic if vsock_loopback is not available

Browse Source 
test_vsock_thread_backend_vsock() and test_vsock_thread_vsock_backend()
tests use VMADDR_CID_LOCAL which is provided by the `vsock_loopback`
kernel module.

If `vsock_loopback` kernel module is not loaded, these tests will fail
later with unclear messages, so it can be hard to debug.

Let's fail early and print a message with the requirement.
