AU: shift to use new TMPDIR-enabled temp file

The main change here is that delta generator will now create all
temporary files in TMPDIR, if set. Other than that, we're converting all
other temporary file/directory creation to use the new functions.

- All temps of the form "/tmp/foo" are converted to "foo": this
  preserves the behavior in the default case (where TMPDIR is not set),
  yet will do the right thing if run with a different TMPDIR.

- A few other cases (for example, temp file created relative to the
  current working directory) will now be created in TMPDIR or /tmp.
  These are all in unit tests and the transition makes sense anyway.

Note that two temp file/directory creation calls in actual UE code were
using "/tmp/..." and were not changed. This will ensure that they are
resilient to TMPDIR changes and will always be allocated in the same
(hard-coded) location.
