Create: change default metadata type to 1.2

Change default - again, sorry.

v1.1 causes problems as the conflicts with a boot sector, whether on
the whole device or in a partition.  I guess the rule is they you
aren't allowed to use the first sector in general.

v1.2 is mostly just as good and avoid boot-sector problems so default
to that instead.
