Update docs for serde_if_integer128

Browse Source 
The docs imply that the only consideration for using the
serde_if_integer128 macro is support for older versions of Rust, but
Serde's build configuration for 128-bit integers is also gated on the
target platform. For example, if Serde is being compiled for an
emscripten target, then it will not provide 128-bit integer APIs.
