perf test: Switch to new perf_mmap__read_event() interface for tp fields 



The perf test 'syscalls:sys_enter_openat event fields' still use the
legacy interface.

No functional change.

Committer notes:

Testing it:

  # perf test sys_enter_openat
  15: syscalls:sys_enter_openat event fields                : Ok
