[PATCH v2 04/28] buildman: Create temp directory in test setup

[Simon Glass]

Rather than having a few tests handle this themselves, create the
temporary directory in the setUp() method and remove it in tearDown().
This will make it easier to add more tests.

Only testOutput and testGit() actually need it, but it doesn't add to the
test time noticeably to do this for all tests in this file.
