[U-Boot] [PATCH 2/3] add pytest for 'gpt guid' command in sandbox

[alison at peloton-tech.com]

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

Run unit tests for the 'gpt guid' command, making use of the disk.raw
block device created by test/gpt/make-test-disk.sh script.  Remove
this device at the end of the tests.
