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