Gittrac #4312:  Added failure subroutines to some DAGMan tests that
were missing them; also prepended "Error" to fatal error messages in
those tests.  (Note:  this change isn't directly part of #4312, but
I found these problems in the course of working on that ticket, so
I'm including the changes under that umbrella.)
