Subject: [PATCH 1/2] Disable `rustc-serialize` derives for future compilers

The built-in derives are being [removed], but crater showed problems
with crates depending on `num v0.1`, where this feature is enabled by
default. With this PR, we detect the missing built-ins and disable the
derives, adding a build-script warning about it. Cargo won't show such
warnings by default from non-path dependencies, unless the build fails.

For `num` itself, this mostly just amounts to a dependency bump.

[removed]: https://github.com/rust-lang/rust/pull/134272
