Broken Symlinks when Ubuntu 24.04 with Python plugin and `override-prime` is used
Metadata
Current evaluation
Ubuntu 24.04 Python parts using override-prime still produce broken usrmerge symlinks; a maintainer acknowledged the limitation, but the case remains unresolved.
Suggested action: keep open
Reason: Maintainer tigarmo explicitly called this an unfortunate limitation, and no resolving change is cited. The current _python_usrmerge_fix still requires lib64 in step_info.state.files, consistent with override-prime bypassing the fix, but the missing build log and unanswered question about the final indico.wsgi path require further verification.

Issue body
### Bug Description
The [fix for Ubuntu 24.04 with Python plugin](https://github.com/canonical/rockcraft/pull/498) doesn't work when `override-prime` is used. Doesn't even work when we use `craftctl default` in the `override-prime`.
### To Reproduce
Write a rock with Ubuntu 24.04 and Python plugin and do something in `override-prime`.
### Environment
Multipass
Ubuntu 22.04
Rockcraft 1.5.3
