Fix mktemp invocation to work on Mac OS X and Linux

mktemp on Mac OS X (and probably all BSDs) just returns an error when
invoked without any arguments.  The -t option used in this change is
interpreted differently on Mac OS X and Linux, and is deprecated on
Linux, but this invocation works as expected on both.

Another alternative would be to use Python's tempfile module:
