[PATCH v8 perf,bpf 11/15] perf: add -lopcodes to feature-libbfd

Both libbfd and libopcodes are distributed with binutil-dev/devel. When
libbfd presents, it is OK to assume libopcodes also presents. This has
been a safe assumption for bpftool.

This patch adds -lopcodes to perf/Makefile.config. libopcodes will be
used in the next commit for bpf annotation.
