perf tools: Apply tracepoint event definition options to BPF script

Users can pass options to tracepoints defined in the BPF script.  For
example:

  # perf record -e ./test.c/no-inherit/ bash
  # dd if=/dev/zero of=/dev/null count=10000
  # exit
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.022 MB perf.data (139 samples) ]

  (no-inherit works, only the sys_read issued by bash are captured, at
   least 10000 sys_read issued by dd are skipped.)

test.c:

  #define SEC(NAME) __attribute__((section(NAME), used))
  SEC("func=sys_read")
  int bpf_func__sys_read(void *ctx)
  {
      return 1;
  }
  char _license[] SEC("license") = "GPL";
  int _version SEC("version") = LINUX_VERSION_CODE;

no-inherit is applied to the kprobe event defined in test.c.
