perf symbols: Workaround objdump difficulties with kcore
The objdump tool fails to annotate module symbols when looking at kcore. Workaround this by extracting object code from kcore and putting it in a temporary file for objdump to use instead. The temporary file is created to look like kcore but contains only the function being disassembled.
