TLibC should be a separate cell from the kernel

[SamuraiCrow]

I just checked back recently and found that a C runtime has been introduced. I realize it is necessary for most software to have and that most software is not written in Rust yet. With any non-safe language, however, the intralingual design gets lost if the C runtime is not an optional package.

My request is that the C runtime be moved to a separate repository within the Theseus-OS organization. I don't plan on using it for now. Perhaps when safety features (like SafeC or D have) can be introduced and safety can be mandated, then I'll look into it.
