Move `eo-sys` to `eo-runtime`

[maxonfjvipon]

The library eo-sys contains 3 objects which interact with operating system via system calls. They should be part of eo-runtime as well as io subpackage.

@maxonfjvipon thanks for the report, here is a feedback:

Problems

• The bug report is missing a precise description of the issue or the bug, appearing more as a suggestion or task than a bug report.
• The report fails to provide details about the environment (Operating System, software version, etc.) where the bug was encountered.
• Absence of steps to reproduce the bug in the report, a crucial element for developers to replicate the issue and identify the root cause.

I would recommend including specific steps to reproduce the issue to improve the clarity and usefulness of the bug report.

Please fix the bug report in order it to get resolved faster. Analyzed with gpt-4

[maxonfjvipon]

The important thing here is that we should not introduce dependencies into eo-runtime meanwhile eo-sys depends on com.sun.jna for making system calls
