perf test: Switch to new perf_mmap__read_event() interface for bpf

Browse Source 
The perf test 'bpf' still use the legacy interface.

No functional change.

Committer notes:

Tested with:

  # perf test bpf
  39: BPF filter                                            :
  39.1: Basic BPF filtering                                 : Ok
  39.2: BPF pinning                                         : Ok
  39.3: BPF prologue generation                             : Ok
  39.4: BPF relocation checker                              : Ok
