Add missing link dependency

[wmtan]

The standalone tool edmProvDump needs the dictionaries in DataFormats/WrappedStdDictionaries to function properly. This link dependency was missing from the build file. The tool depended on automatic loading of dictionaries to dynamically load these dictionaries. This pull request simply adds the missing link dependency.

Is this ROOT6 specific?

[wmtan]

The need for it is ROOT6 specific. It is not yet fully understood why the dictionary is not automatically loaded in ROOT6.
This will not break ROOT5, but it may cause a library to be linked in unnecessarily.
In hindsight, the description of this pull request above is actually wrong. edmProvDump needs DataFormats/WrappedStdDictionaries if and only if the file being dumped contains an object of a built in or an STL container of a built-in. In a framework unit test, this is the case, and the test fails without this request.
We should figure out why edmPluginDump does not load the dictionary automatically in ROOT6.
In hindsight, this may be a workaround rather than a real fix. So, I don't think it should be added for ROOT5.
