[PULL 57/91] tests/qtest/vhost-user-blk-test: use memory-backend-shm

[Michael S. Tsirkin]

From: Stefano Garzarella <sgarzare@redhat.com>

`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.

Since we are here, let`s remove `share=on` which is the default for shm
(and also for memfd).
