remove extraneous note on `UnableToRunDsymutil` diagnostic
If I understand [this FIXME](1367827eac/compiler/rustc_macros/src/diagnostics/diagnostic.rs (L205)) correctly, it seems we don't yet validate subdiagnostics, so `#[note]` and co in the `#[derive(Diagnostic]` item could be out-of-sync with the fluent message, without causing compile errors.
It was the case for `rustc_codegen_ssa::errors::UnableToRunDsymutil`, causing the ICE in #124392.
I've grepped and scripted my way through most of our diagnostics structs and fluent bundles and the above was the only such extraneous `#[note]`/`#[note(name)]`/`#[help]`/`#[warning]` I could find, so hopefully there aren't many others like it.
I haven't checked if the opposite can happen, a `.note = ` in a fluent message that is lacking a corresponding `#[note]` on the struct and not causing an error, but maybe it's possible?
