Set home-cluster while creating an array
The home-cluster is stored in the bitmap super block of the
array. The device can be assembled on a cluster with the
cluster name same as the one recorded in the bitmap.
If home-cluster is not specified, this is auto-detected using
dlopen corosync cmap library.
neilb: allow code to compile when corosync-devel is not installed.
