[PATCH] doc: sandbox: replace sgdisk input with options

[Simon Glass]

The input provided to sgdisk is in fact aimed for sfdisk. The use of
sgdisk and sfdisk, coming from different projects, is not the same.

So, this commit translates the sfdisk-formatted input into
sgdisk-compatible options. Partitions are not modified.
