wasm32-unknown-emscripten expects the rust_eh_personality symbol

The `wasm32-unknown-emscripten` expects the `rust_eh_personality` symbol to be there, but a cfg checking for `target_arch = "wasm32"` which was meant to remove the symbol from the `wasm32-unknown-unknown` target, didn't check for whether `emscripten` is targeted or not, so the symbol accidentally got filtered out there as well.

Fixes #55276
