C API: Safer function pointer casting 
See https://github.com/NixOS/nix/pull/8699#discussion_r1554312181

Casting a function pointer to `void*` is undefined behavior in the C
spec, since there are platforms with different sizes for these two kinds
of pointers. A safe alternative might be `void (*callback)()`
