Framework: CDash interprets failed shared library load as a "not run" rather than as a fail

As I discovered from our testing, if a program cannot find a shared library at run time (and the test fails to run), cdash reports that as a "Not Run" which has no useful screen output. This case really ought to be a run failure, so we can see the effect of the failed library load.
