TrigEgammaMonitoring: Dependency fix

TrigEgammaAnalysisBaseTool has a dependency on LuminosityCondDataOnline.
These tools are used by TrigEgammaMonTool/HLTEgammaMon.
However, that tool does not use ToolHandleArray in the standard way,
so the dependency doesn't get automatically propagated.
So just add the dependency by hand.

Needed to fix crashes with q220 with --thread=1.
