[SPARK-13474][PROJECT INFRA] Update packaging scripts to push artifacts to home.apache.org

Due to the people.apache.org -> home.apache.org migration, we need to update our packaging scripts to publish artifacts to the new server. Because the new server only supports sftp instead of ssh, we need to update the scripts to use lftp instead of ssh + rsync.

Closes #11350 from JoshRosen/update-release-scripts-for-apache-home.
