Provide a name for a module library in fest-swing

When building the release bundle with UI tests,
LayoutBuilder.getLibraryName fails while processing the module libraries
in fest-swing, as they have multiple roots. This change names the
library so LayoutBuilder does not have to attempt to infer it from the
names of the jars therein.
