super1: encourage data alignment on 1Meg boundary

For 1.1 and 1.2 metadata where data_offset is not zero,
it is important to align the data_offset to underlying
block size.

We don't currently have access to the particular device
in avail_size so just try to force to a 1Meg boundary.

Also default 1.x metadata to 1.2 as documented.
