Song Liu 7b612e291a perf tools: Synthesize PERF_RECORD_* for loaded BPF programs 
This patch synthesize PERF_RECORD_KSYMBOL and PERF_RECORD_BPF_EVENT for
BPF programs loaded before perf-record. This is achieved by gathering
information about all BPF programs via sys_bpf.

Committer notes:

Fix the build on some older systems such as amazonlinux:1 where it was
breaking with:

  util/bpf-event.c: In function 'perf_event__synthesize_one_bpf_prog':
  util/bpf-event.c:52:9: error: missing initializer for field 'type' of 'struct bpf_prog_info' [-Werror=missing-field-initializers]
    struct bpf_prog_info info = {};
           ^
  In file included from /git/linux/tools/lib/bpf/bpf.h:26:0,
                   from util/bpf-event.c:3:
  /git/linux/tools/include/uapi/linux/bpf.h:2699:8: note: 'type' declared here
    __u32 type;
          ^
  cc1: all warnings being treated as errors

Further fix on a centos:6 system:

  cc1: warnings being treated as errors
  util/bpf-event.c: In function 'perf_event__synthesize_one_bpf_prog':
  util/bpf-event.c:50: error: 'func_info_rec_size' may be used uninitialized in this function

The compiler is wrong, but to silence it, initialize that variable to
zero.

One more fix, this time for debian:experimental-x-mips, x-mips64 and
x-mipsel:

  util/bpf-event.c: In function 'perf_event__synthesize_one_bpf_prog':
  util/bpf-event.c:93:16: error: implicit declaration of function 'calloc' [-Werror=implicit-function-declaration]
     func_infos = calloc(sub_prog_cnt, func_info_rec_size);
                  ^~~~~~
  util/bpf-event.c:93:16: error: incompatible implicit declaration of built-in function 'calloc' [-Werror]
  util/bpf-event.c:93:16: note: include '<stdlib.h>' or provide a declaration of 'calloc'

Add the missing header.

Committer testing:
