Update librmm conda recipe (#997)

This PR updates the `librmm` `conda` recipe with some learnings from rapidsai/cudf#10326.

Namely that the top-level `build.sh` script is the only feasible approach for consolidating the recipes.

The implication of these changes is that any shared libraries used in the top-level build must now manually be specified as `run` dependencies of the corresponding `outputs` package. To help reduce the amount of duplication of version specifications for these packages, dependency versions can be specified in `conda/recipes/librmm/conda_build_config.yaml`. The exception here is the version spec used for `cudatoolkit` since that comes from an environment variable in the CI process.
