Remove useless -Wno-long-long option

Browse Source 
According to GCC doc, -Wlong-long: Warn if long long type is used.
This is enabled by either -Wpedantic or -Wtraditional in ISO C90
and C++98 modes. To inhibit the warning messages, use -Wno-long-long.

OpenCV 4.x requires C++11. As result, this option is useless.
