Merge bitcoin#31651: ci: Turn CentOS task into native one

fabefd9 ci: Turn CentOS task into native one (MarcoFalke)

Pull request description:

  Cross-compiling to `i686-pc-linux-gnu` on CentOS in the CI is mostly redundant with the `ci/test/00_setup_env_i686_multiprocess.sh` task (albeit it using clang):

  https://github.com/bitcoin/bitcoin/blob/35bf426e02210c1bbb04926f4ca2e0285fbfcd11/ci/test/00_setup_env_i686_multiprocess.sh#L9-L12

  One task seems sufficient as a sanity check, given that there seems to be no real demand for this architecture anyway.

  Turning the task into a native one makes it possible to run the task natively on aarch64 or any other supported architecture.

  Also, remove the install of the `lbzip2` package, which is unused since commit a46065e

  Also, remove the `CONFIG_SHELL` env var, which is unused since the cmake migration. (`CONFIG_SHELL` in depends is still kept).
