disable proc-macro re-export inlining

Proc-macros don't emit their attributes or source spans across crates.
This means that rustdoc can't actually see the docs of a proc-macro if
it wasn't defined in the active crate, and attempting to inline it
creates an empty page with no docs or source link. In lieu of attempting
to fix that immediately, this commit forces proc-macro re-exports to
never inline, which at least creates usable links to complete
documentation.
