[Buildroot] [PATCH 1/1] create-boot-sd.sh: fix script for sfdisk (>=2.26)

[Georges Savoundararadj]

"Since version 2.26, sfdisk [...] no longer provides any functionality
for CHS (Cylinder-Head-Sector) addressing." [1]

The unit used in this script is the cylinder which is not supported in
the latest versions of sfdisk. However, it supports the deprecated option
"--unit S" that allows to keep the retro-compatibility with the older
versions of sfdisk if we use the sector unit.

This commit converts the offset and size from the cylinder unit (8 bytes)
to the sector unit (512 bytes).
