[PATCH net-next v4 11/12] selftests/vsock: add vsock_loopback module loading

[Bobby Eshleman]

From: Bobby Eshleman <bobbyeshleman@xxxxxxxx>

Add vsock_loopback module loading to the loopback test so that vmtest.sh
can be used for kernels built with loopback as a module.

This is not technically a fix as kselftest expects loopback to be
built-in already (defined in selftests/vsock/config). This is useful
only for using vmtest.sh outside of kselftest.
