Most of the tests work with local storage options. Some support S3
options as well. Whatever it is, when creating an sstable, tests need to
put proper "dir" on the options, this patch does so.
In fact, storage options for tests are created together with the
test-env, and ideally this is the place where dir should be assigned on
it. However, there are still places that explicitly specify path they
want to see sstables at, for those the new temporary options should be
constructed.
