Subject: [PATCH] base image: Explicitly call kpartx
qemu-nbd currently available in CentOS 7 does not add partition
mappings automatically for NBD devices, so add explicit `kpartx`
calls.
On rare occassions, mapper bindings created by kpartx take longer
to show up, leading to errors when we try to mount them on.
Bring back the hardcoded delay to bypass such issues.
