block/export: disable VHOST_USER_PROTOCOL_F_INFLIGHT_SHMFD for now

The vhost-user in-flight shmfd feature has not been tested with
qemu-storage-daemon's vhost-user-blk server. Disable this optional
feature for now because it requires MFD_ALLOW_SEALING, which is not
available in some CI environments.

If we need this feature in the future it can be re-enabled after
testing.
