Allowing DerivationFrameworkAnalysisTests in AthDerivation
This will solve a warning during the build of 21.2,AthDerivation by adding back the package DerivationFrameworkAnalysisTests. It should build successfully in AthDerivation, and we can afford to run its tests there (this will allow that). No reason I can see not to have it there as well.
