wasmtime example broken

[mkroening]

Since #617, wasmtime returns:

[0][INFO] Try to initialize network!
[0][INFO] Try to initialize uhyve filesystem
INFO  [wasmtime_demo] Start Wasmtime demo!
Error: WebAssembly translation error

Caused by:
    Invalid input WebAssembly code at offset 738: zero byte expected
Number of interrupts
[0][FPU]: 3
[0][INFO] shutting down with code 1
Error: QEMU exit code: Some(1)

This happens since nightly-2024-08-01: rust-lang/rust@f8060d2...28a58f2

Maybe it's the LLVM upgrade?

[mkroening]

This is due to bytecodealliance/wasmtime#9130.
