### What changes were proposed in this pull request? This PR aims to upgrade `zstd-jni` to 1.5.0-1, which uses `zstd` version 1.5.0. ### Why are the changes needed? Major improvements to Zstd support are targeted for the upcoming 3.2.0 release of Spark. Zstd 1.5.0 introduces significant compression (+25% to 140%) and decompression (~15%) speed improvements in benchmarks described in more detail on the releases page: - https://github.com/facebook/zstd/releases/tag/v1.5.0 ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Build passes build tests, but the benchmark tests seem flaky. I am unsure if this change is responsible. The error is: ``` Running org.apache.spark.rdd.CoalescedRDDBenchmark: 21/06/08 18:53:10 ERROR SparkContext: Failed to add file:/home/runner/work/spark/spark/./core/target/scala-2.12/spark-core_2.12-3.2.0-SNAPSHOT-tests.jar to Spark environment java.lang.IllegalArgumentException: requirement failed: File spark-core_2.12-3.2.0-SNAPSHOT-tests.jar was already registered with a different path (old path = /home/runner/work/spark/spark/core/target/scala-2.12/spark-core_2.12-3.2.0-SNAPSHOT-tests.jar, new path = /home/runner/work/spark/spark/./core/target/scala-2.12/spark-core_2.12-3.2.0-SNAPSHOT-tests.jar ``` https://github.com/dchristle/spark/runs/2776123749?check_suite_focus=true cc: @dongjoon-hyun -- This is an automated message from the Apache Git Service.
