[Qemu-devel] [PATCH v2 9/9] tests: use memfd in vhost-user-test

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

This will exercise the memfd memory backend and should generally be
better for testing than memory-backend-file (thanks to anonymous files
and sealing).

The test is already Linux-specific, but will now require Linux with
memfd (since 3.17).
