Force test suite to observe morph.conf tempdir

This change, suggested in story #16, causes the testing suite to use
the user-defined tempdir in /etc/morph.conf if it exists or continue
using /tmp if not. This will prevent the test suite from filling drives
that are not intended to be used for development work.
