Disable zstd decompression support with libmagic

What does this MR do?

ruby-magic updated to libmagic v5.44, which added support for zstd decompression support. Unlike most of our other builders, it appears that AmazonLinux 2022 needs libzstd to support dnf.

With ruby-magic v0.6.0 in gitlab!114641 (merged), we can use the --with-magic-flags to disable this functionality outright since this system dependency may not be safe to use.
