Update ctru-rs for the latest libctru release

[Meziu]

libctru just released the latest 2.1.2 version: https://github.com/devkitPro/libctru/releases/tag/v2.1.2.

There have been numerous changes, but the one that influences us the most is the native addition of clock_gettime. We should update our repos accordingly.

Furthermore, @ian-h-chamberlain's thread changes have been released! Does this help with the thread_localPRs?

PRs to be merged:

• Refresh libctru to the latest version #90
• Update for the latest libctru version shim-3ds#15
• Update to latest ctru-sys and toolchain pthread-3ds#20

Yes, we should be able to re-enable #[thread_local] finally on Rust main now! I also wonder if citro3d-rs will need any updates to account for the changes made in ctru-sys... If I have some time this weekend I'll take a look at both of those and will link here once I have PRs.

It looks like some of the APIs changed to use size_t instead of u32 now too? Nice to have less as casts

@rust3ds/active Great stuff. I’ve merged the changes, I remind everybody to do (dkp-)pacman -Syu cargo clean and cargo update before using the toolchain. 😃
