Namhyung Kim e53de7b65a perf lock contention: Fix struct rq lock access 
The BPF CO-RE's ignore suffix rule requires three underscores.
Otherwise it'd fail like below:

  $ sudo perf lock contention -ab
  libbpf: prog 'collect_lock_syms': BPF program load failed: Invalid argument
  libbpf: prog 'collect_lock_syms': -- BEGIN PROG LOAD LOG --
  reg type unsupported for arg#0 function collect_lock_syms#380
  ; int BPF_PROG(collect_lock_syms)
  0: (b7) r6 = 0                        ; R6_w=0
  1: (b7) r7 = 0                        ; R7_w=0
  2: (b7) r9 = 1                        ; R9_w=1
  3: <invalid CO-RE relocation>
  failed to resolve CO-RE relocation <byte_off> [381] struct rq__new.__lock (0:0 @ offset 0)
