[ruby/zlib] Workaround: Fix test failures on Ubuntu jammy s390x.
This commit fixes the test failures on the zlib in Ubuntu jammy s390x.
According to the <https://packages.ubuntu.com/jammy-updates/zlib1g> -
`zlib_1.2.11.dfsg-2ubuntu9.2.debian.tar.xz`,
the zlib deb package is applying the patch 410.patch (madler/zlib#410), and
configured by `./configure --dfltcc` on Ubuntu jammy s390x. The `--dfltcc`
is to enable the deflate algorithm in hardware.
It produces a different (but still valid) compressed byte stream, and causes
the test failures in ruby/zlib. As a workaround, set the environment variable
`DFLTCC=0` disabling the implementation in zlib on s390x to the failing tests.
Note we need to test in a child Ruby process with `assert_separately` to test
on the `DFLTCC=0` set by the parent Ruby process.
