[CI] Use dedicated Apache mirror for Thrift

Update the premerge build to download Arrow's Apache Thrift tarball through sw-spark-apache-remote instead of sw-spark-maven/apache-remote.

The dedicated Generic Artifactory remote is backed by archive.apache.org and automatically caches Apache tarballs, avoiding the manual uploads required by the Maven repository path.

Continue authenticating through ~/.netrc with CMAKE_NETRC=OPTIONAL, and run the cuDF build through common.shWithRedactedAuthorization so CMake/libcurl failures cannot expose credentials in the Jenkins console while pipefail preserves the original command failure.
