[PATCH for-9.1 v3 10/11] tests/qtest/vhost-user-blk-test: use memory-backend-shm

[Stefano Garzarella]

`memory-backend-memfd` is available only on Linux while the new
`memory-backend-shm` can be used on any POSIX-compliant operating
system. Let's use it so we can run the test in multiple environments.
