[BUG] Drop CentOS7 support for java/ci docker build

[NvTimLiu]

Describe the bug We plan to drop CentOS 7 (which uses glibc 2.17) RAPIDS 24.06. The java/ci/Dockerfile.centos7 need to be change/upgrade to support running build in Rocky8 Docker container, refor or to :

https://docs.rapids.ai/notices/rsn0037/

https://github.com/rapidsai/build-planning/issues/23

The new minimum glibc supported by RAPIDS will become 2.28 (used by Rocky 8), because that is the oldest glibc of any operating system we currently support.

Built out amd64/arm64 cudf JNI jars on Rocky8, running some tests to see if any GLIBC issues.
