Avoid Using Deprecated Functions in Deprecated Code

`lib/deprecated` is no longer built by zstd's bundled build files. However,
users may try to build these files when they import the source tree into
their own build systems. And if they have `-Wdeprecated-declarations` on,
this can produce warnings.

This PR migrates these files away from using deprecated declarations.

This addresses #2767.
