[mlir][test] Fix IR/AttributeTest.cpp compilation on Solaris

The `IR/AttributeTest.cpp` test fails to compile on Solaris:

  /vol/llvm/src/llvm-project/local/mlir/unittests/IR/AttributeTest.cpp:223:36: error: no matching function for call to 'allocate'
        AttrT::get(type, "resource", UnmanagedAsmResourceBlob::allocate(data));

I suspect this happens because `char` is `signed` by default on Solaris.

Tested on `amd64-pc-solaris2.11` and `sparcv9-sun-solaris2.11`.
