Do not use blanket impls when building for `c_bindings`

The C bindings generator isn't capable of figuring out if a blanket
impl applies in a given context, and instead opts to always write
out any relevant impl's for a trait. Thus, blanket impls should be
disabled when building with `#[cfg(c_bindings)]`.
