disk/prep: if no 9fat, reserve space for plan9 partition table in autopart (thanks Shamar)
usually, the plan9 partition table is contained in
the first 9fat partition after the pbs/fat header,
but when no 9fat partition is requested, we have
to make sure partitions wont overlap the partition
table (start at sector offset >= 2).
