add missing compiler definitions of RCPPUTILS_VERSION

[saikishor]

Similar to ros-controls/ros2_control#1440, there is a missing compile definition of the rcpputils to use the proper non-deprecated namespace of RollingMeanAccumulator library starting from Humble, these compile definitions are needed to use the proper version.

I have opened a PR on rcpputils repo also to have the version.h header in their library, It's waiting to be merged, once it is merged, we can directly use the version.h instead of these compile definitions.

Fine for me until ros2/rcpputils#190 gets merged.
