Adding a macro on NetSocketPosix to pick the right type for FIONREAD len

On Windows, `ioctlsocket` returns `len` as an unsigned long.
On Posix, `ioctl` returns `len` as an int.
This aims to fix #41287 bug, which was seen on Linux.
The implementation is just a new macro that is set with the proper type
for each platform.
