Drop the wasm32 builder
This builder tested the wasm32-unknown-emscripten target, which is tier 2 (and so not eligible for testing). In the recent beta promotion, we ran into a problem with this target: emscripten doesn't support passing environment variables into the std environment, so we can't enable RUSTC_BOOTSTRAP for libtest in order to pass -Zunstable-options. We worked around this for the beta/stable branches, but given this problem, and its tier 2 status, just dropping the target's tests entirely seems warranted. Downgrading to tier 3 may also be a good idea, but that is a separate conversation not proposed here.
