iotests: add 208 nbd-server + blockdev-snapshot-sync test case
This test case adds an NBD server export and then invokes
blockdev-snapshot-sync, which changes the BlockDriverState node that the
NBD server's BlockBackend points to. This is an interesting scenario to
test and exercises the code path fixed by the previous commit.
