Fixes for build in "super-project" context
- remove unneeded include of
GaudiKernel/ParticleProperty.h
(see !3723 (merged)) - add link to RichFutureUtils (implicitly required by !3472 (merged))
This is a just a minor change that might only affect the build, so there's no need of a ci-test and a build in lhcb-gaudi-head is enough.
