perf test: Remove exclusive tag from perf trace tests

Now it's safe to run multiple perf trace commands at the same time.
Let's make them non-exclusive so that they can run in parallel.

  $ sudo perf test 'perf trace'
  113: Check open filename arg using perf trace + vfs_getname          : Skip
  114: perf trace enum augmentation tests                              : Ok
  115: perf trace BTF general tests                                    : Ok
  116: perf trace exit race                                            : Ok
  117: perf trace record and replay                                    : Ok
  118: perf trace summary                                              : Ok
