sfdisk: fix --append to PT with gaps
sfdisk trying to be more smart than libfdisk when analyze if we can
append to the current PT. libfdisk is able to use unused partition
to create a new one (if partno not strictly specified), but sfdisk
assumes that we can add partition to extended partition only.
