Revert "Add compile-library by default on pylibraft build" (#2300)

Partial reversion of #2090

The unintended consequence of this PR was to cause conda builds of pylibraft to rebuild libraft. As a result, since mid-24.04 we've seen the following: pylibraft conda builds have gone from 15-30 mins to 75-90 mins; pylibraft conda packages are fully repackaging libraft; and therefore, pylibraft conda packages have gone from ~2-3MB to ~300MB. A future PR may attempt to improve the developer experience again, at which point we should keep an eye out for similar regressions.
