Subject: [PATCH] wasmedge: Fix use supported llvm version by the project

Trying to build this package build because the project use deprecated
`LLVMBuildNUWNeg` (that was deprecated between v17 and v19 of llvm).
The `0.14.1` state that it support the version 17 of `llvm`.

So I've fixed the build by using that stated version.
