test/e2e: fix incorrect usage of CreateTempDirInTempDir()

Creating a new diretory results in the test leaking it when it is not
removed via a defer call. All tests have already access to
`podmanTest.TempDir` which will be automatically removed in the
`AfterEach()` block.

While some test were fine other forgot the defer call. To keep the test
consitent and prevent other from making the same mistake convert all
users to `podmanTest.TempDir`. `CreateTempDirInTempDir()` is only used
for the `podmanTest.Setup()` call.
