addpref.m: Recode BIST test to work with multiple running instances of Octave.

When running multiple instances of the Octave test suit (such as on the build
bots) there can be conflict over the file /tmp/.octave_prefs.  Avoid that
conflict by having a per-Octave-instance directory.
* addpref.m: Use tempname() and mkdir() to create a per-Octave-instance
directory used for BIST test.  Delete the temporary directory at the end
of the test.
