rustc_llvm: unwrap LLVMMetadataRef before casting
Directly casting the opaque pointer was [reported] to cause an
"incomplete type" error with GCC 9.3:
```
llvm-wrapper/RustWrapper.cpp:939:31: required from here
/usr/include/c++/9.3/type_traits:1301:12: error: invalid use of incomplete type 'struct LLVMOpaqueMetadata'
1301 | struct is_base_of
| ^~~~~~~~~~

from llvm-wrapper/RustWrapper.cpp:1:
[...]/rust/src/llvm-project/llvm/include/llvm-c/Types.h:89:16: note: forward declaration of 'struct LLVMOpaqueMetadata'
89 | typedef struct LLVMOpaqueMetadata *LLVMMetadataRef;

```

A simple `unwrap` fixes the issue.
