Subject: [PATCH 266/270] osdep/freebsd: Fix partition calculation for EBR
 entries

For EBR partitions, "start" is the relative starting sector of the EBR
header itself, whereas "offset" is the relative starting byte of the
partition's contents, excluding the EBR header and any padding. Thus we
must use "offset", and divide by the sector size to convert to sectors.

Fixes Debian bug #923253.
