Use `report_in_external_macro` in internal lints

[Centril]

Filing this since @eddyb had the idea and so that we don't forget.

It should be as easy (unless I'm overlooking something) as adding report_in_external_macro: true to all declare_tool_lint invocations

rust/src/librustc/lint/internal.rs

Line 53 in 56237d7

declare_tool_lint! {

and then fixing the fallout (changing imports as described by the lint)

[afnanenayet]

I'd like to handle this
