See failed pax-ic-good-opt-off. But the failure should not be in the changes that have been made.

Thanks @leborchuk . I will continue to improve this PR later for a better code style.

Updates:

In this PR, just improve two obvious places:

• Remove RPM artifacts after installation
• Remove source tarball after extraction

Let's see how the tests will go.

The changes work for good-opt-on and good-opt-off, but cbdb-parallel always failed. I will explore more to try to fix it.
