selftests/bpf: use host CPU features in JIT disassembler

Browse source

Pass the host CPU name and feature string to
LLVMCreateDisasmCPUFeatures() instead of using LLVMCreateDisasm(), so
the disassembler correctly decodes CPU-specific instructions and
extensions such as RISC-V compressed and vector instructions.
