compiletest: Remove the "wasm32-bare" alias for `wasm32-unknown-unknown`

- Follow-up to https://github.com/rust-lang/rust/pull/148969

This "wasm32-bare" alias, understood by compiletest's `//@ ignore-wasm32-bare` and `//@ only-wasm32-bare` directives, dates all the way back to the original introduction of the `wasm32-unknown-unknown` target in https://github.com/rust-lang/rust/pull/45905.

But there is no compelling reason to use an alias instead of the full target name.
