test: use T.TempDir to create temporary test directory (#3725)

Prior to this commit, temporary directories in tests were created using
`filepath.Join` and `os.MkdirAll`.

This commit replaces `os.MkdirAll` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
