Update clang-sys

[theoparis]

Please update clang-sys to 1.8.1 in bindgen, previous versions do not handle static linking or libc++ properly.

Additionally I can't update clang-sys myself:

error: failed to select a version for `clang-sys`.
    ... required by package `bindgen v0.49.3 (https://github.com/rust-lang/rust-bindgen#ad0bf8e6)`
    ... which satisfies git dependency `bindgen` of package `nixc v0.0.1 (/home/theo/Documents/nixc)`
versions that meet the requirements `^0.28.0` are: 0.28.1, 0.28.0

the package `clang-sys` links to the native library `clang`, but it conflicts with a previous package which links to `clang` as well:
package `clang-sys v1.8.2 (https://github.com/KyleMayes/clang-sys#e4c9b7ef)`
    ... which satisfies git dependency `clang-sys` of package `nixc v0.0.1 (/home/theo/Documents/nixc)`
Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the `links = "clang"` value. For more information, see https://doc.rust-lang.org/cargo/reference/resolver.html#links.

Have you tried updating bindgen to the most recent version before trying to update clang-sys?

Not sure why I had an old version of bindgen here. However I am running into a new issue where I get undefined references to zstd, possibly due to using a static zstd library. My bad, the llvm build I used was using libzstd.so for some reason.
