rgw/tracing: unify SO version numbers within librgw2 package

The librgw2 package contains several SO files. Two of those - librgw_op_tp.so
and librgw_rados_tp.so - had a different version number than the main librgw.

This was a violation of the openSUSE Shared Library Packaging Policy [1] but it
also seems like a "violation" of common sense.
