PATCH 1/1 perf: make annotate demangle symbols

Perf report is demangling symbols but not annotate. The former uses internal demangling via libbdf or libiberty. The latter executes objdump which by default does not demangle symbols.

This patch adds the -C option to the objdump cmdline to enable symbol demangling.
