[U-Boot] [PATCH v7 4/9] sandbox: README: fix partition command invocation

[alison at peloton-tech.com]

From: Alison Chaiken <alison at peloton-tech.com>

The instructions for creating a disk image that are presently in
README.sandbox fail because sfdisk doesn't know about GPT.

Changes since v6: none.
