global: reflect upgrade of zstd to 1.5.4

An error message change resulted in a changed test. Pretty minor.

Rust complained about new fields on `ZSTD_frameHeader`. So we added
them.

Static APIs are now prefixed by new variants of `ZSTDLIB_API`. So
we strip those as well to make cffi parsing happy on non-Windows.

Closes #190.
