On powerpc, immediate load instructions are sign extended. In case of unsigned types, arguments should be explicitly zero-extended by the caller. For kfunc call, this needs to be handled in the JIT code. In bpf_kfunc_call_test4(), that tests for sign-extension of signed argument types in kfunc calls, add some additional failure checks. And add bpf_kfunc_call_test5() to test zero-extension of unsigned argument types in kfunc calls.
