pvs: new attr and field for unchosen duplicate device
When there are duplicate devices for a PV, one device
is preferred and chosen to exist in the VG. The other
devices are not used by lvm, but are displayed by pvs
with a new PV attr "d", indicating that they are
unchosen duplicate PVs.
The "duplicate" reporting field is set to "duplicate"
when the PV is an unchosen duplicate, and that field
is blank for the chosen PV.
