Wang Nan 5dbd16c0c9 perf bpf: Allow attaching BPF programs to modules symbols

By extending the syntax of BPF object section names, this patch allows
users to attach BPF programs to symbols in modules. For example:

  SEC("module=i915;"
      "parse_cmds=i915_parse_cmds")
  int parse_cmds(void *ctx)
  {
      return 1;
  }

The implementation is very simple: like what 'perf probe' does, for module,
fill 'uprobe' field in 'struct perf_probe_event'. Other parts will be done
automatically.
