Title: Update restrictions on rustdoc source rendering

The std macros used to be injected with a filename of "", but macros
are now injected with a filename of "<{} macros>" where `{}` is filled in with
the crate name. This updates rustdoc to understand this new system so it'll
render source more frequently.
