hostmem-memfd: disable for systems without sealing support
If seals are not supported, memfd_create() will fail.
Furthermore, there is no way to disable it in this case because
'.seal' property is not registered.
This issue leads to vhost-user-test failures on RHEL 7.2:
qemu-system-x86_64: -object memory-backend-memfd,id=mem,size=2M,: \
failed to create memfd: Invalid argument
and actually breaks the feature on such systems.
Let's restrict memfd backend to systems with sealing support.
