Enable debug logging on tempest

With tempest moving to testr (serially currently) the log level is no

of verbosity in the logging as when running with nose this commit
sets the debug flag on tempest.

Force $DEST to have wider permissions

This is particularly useful in the case where we create the
home directory above and the permissions are too strict.

Other users, such as the apache user, need read/execute for this
directory.
