Add subarray field to supertype.

When loading the metadata for a subarray (super_by_fd), we set
->subarray to be the name read from md/metadata_version so that
getinfo_super can return info about the correct array.

With this we can differentiate between a container and
an array within the container by looking at ->subarray[0].
