Remove stale test skipping - KTLO

[scopreon]

I didn't think this needed a dedicated issue. Happy to create one if necessary.

Describe your changes
Remove the stale PyInstaller version checking in test_relocatable_cores.py.. It now also supports 3.13+3.14.

Testing performed
Test coverage implicitly increased by removing code ;)

Additional context
Found when looking through codebase

Pull request overview

Removes a stale integration-test skip that prevented test_relocatable_cores.py from running on newer Python versions, aligning the test suite with current CI coverage for 3.13/3.14.

Changes:

• Removed pytest.mark.skipif gating the relocatable core integration test on Python version.
• Dropped the now-unused import pytest from the integration test module.
