[jdk17u-dev] RFR: 8303920: Avoid calling out to python in DataDescriptorSignatureMissing test

Fri Aug 23 17:19:40 UTC 2024

Backport of improvements to DataDescriptorSignatureMissing test; already [backported to 21](https://github.com/openjdk/jdk21u-dev/pull/913). Unclean for this [trivial issue fix in 22](https://github.com/openjdk/jdk/commit/34653c1e73452c0e07beb1f5e2eb8029fdb3befc) that adds a bug-id for `@ignore`. Otherwise, it's a clean backport. Affected test passes.
