[PATCH] oeqa/selftest/wic: Fix host contamination issue

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If wic.Wic2.test_gpt_partition_name is run on a system without sfdisk, the test
will currently fail. As done in another test, it needs to use sfdisk from the
wic-tools sysroot. This patch fixes that host contamination issue.
