Build benchmarks in CI

[vyasr]

This PR adds the ability to build benchmarks to build.sh, and passes the necessary option through from the conda build.sh. This change ensures that benchmarks must be able to build against changes in new PRs.

The benchmarks are now built. For instance, the CI log now contains:
