Only install necessary components in conda packages. (#2209)

Closes #2175.

**This PR cuts the binary size of `libraft` by about 50%.** In total, this PR shrinks the binary size of the entire C++ conda channel (the sum of all conda packages produced by `conda/recipes/libraft/meta.yaml`) by around 20%, from 1.5 GB to 1.2 GB. The main difference is dropping the extraneous copy of `libraft.a` (~300 MB) that was shipped in the `libraft` package.
