[lib] nbd: Explicitly map partitions
Certain kernels (e.g. 4.4.0-101+ in Ubuntu) no longer automatically ack the partition table update after `kpartx -a /dev/nbdX`, see [1]. To avoid another dependency on `parted` packages, use `partx` from `util-linux`, which is already installed as a dependency of e2fsprogs.
