BIGTOP-3709. Bring protobuf 2.5.0 back for building HBase on aarch64 and ppc64le.

https://issues.apache.org/jira/browse/BIGTOP-3709

We still need locally installed protobuf-2.5.0 removed by BIGTOP-3438(#915) for building HBase on aarch64 and ppc64le.

I used /usr/local/protobuf-2.5.0 as new destination since /usr/local is the prefix of protobuf-3.7.1 now.

testing this on CentOS 7 aarch64. While the issue caused by protobuf was fixed, got another error on hbase-assembly.

The cause seems to be leveldbjni-all bundled with Hadoop by Bigtop.

I would like to merge this PR first then address license issue in follow-up. filed BIGTOP-3710.

The error in check-aggregate-license of hbase-assembly should be fixed by #921.
