[tests] One test failing on OpenBSD

Tái hiện lỗi filters_sampling trên OpenBSD bằng lệnh kiểm thử được báo cáo và kiểm tra test/filters/test_sampling.cpp quanh các dòng 174-176 và 240-242. Theo dõi kiểm thử RandomSample và dữ liệu đám mây điểm đầu vào của nó để xác định tại sao các tọa độ được lấy mẫu lại khác trên nền tảng này. Hoàn thành khi kiểm thử chạy đạt trên OpenBSD mà vẫn giữ nguyên các kiểm tra sampling hiện có trên các nền tảng khác.

I have a finished port of pcl on OpenBSD and all tests are passing except the following one (apologies for the long code-block, for some reason the <details> block wasn't working):
