Wasm testsuite failure: Inappropriate ioctl for device (os error 25)

When testing the wasm backend, certain test cases currently fail with:

Caused by:
    0: failed to invoke command default
    1: error while executing at wasm backtrace:

    3: Inappropriate ioctl for device (os error 25)

The same error manifest as permission denied (Operation not permitted) using nodejs/uvwasi. The cause is likely https://github.com/bytecodealliance/wasmtime/issues/6239, for the time being I'd say let's simply mark them as expect_broken.
