remove management of UCX system libraries in build scripts (#1053)

For rapidsai/build-planning#57, #1041 switched `ucx-py` over to `libucx` wheels. To test that that was working, it added some code to building scripts to remove system installations of UCX libraries.

That should no longer be necessary as of rapidsai/ci-imgs#154.

This proposes removing that code for managing system dependencies of UCX libraries, to simplify those build scripts a bit.
