BIGTOP-4421. Fix build failure of Hadoop and Alluxio due to node-gyp error.

[iwasakims]

https://issues.apache.org/jira/browse/BIGTOP-4421

We need python2 for rebuilding native libraries required for old node-spss by node-gyp on the architecture for which pre-built native libraries are not provided. Since recent OS distributions do not provide python2, we need another solution here.

I'm bringing back the manifest to install Python 2 from source code removed by BIGTOP-4098(#1262). Previously it was for specific combination of OS and architecture. Now we need this for all OS distributions (supported on Bigtop 3.4.0) on aarch64.

@sekikn Thanks for your comments. I updated the PR and ./gradlew toolchain worked as expected on all of fedora-40, openeuler-22.03, rockylinux-9, debian-12 and ubuntu-24.04 (aarch64).

And packaging of Alluxio and Hadoop succeeded.

@iwasakims Sorry that I missed it, but the first ln should have the -nf option as the second one, since it's not idempotent without that.
+1 otherwise, so you can merge this once you fix it.

Thanks, @sekikn. I updated the option and merged this.
