net: socket: Change socklen_t to be 4 bytes long

There is an issue when zephyr is compiled with native_sim_64 where
size_t is 8 bytes. The socklen_t in specified as 4 bytes in Linux
even for 64 bit builds so we have a conflict between Linux and Zephyr.
To make things work properly, define socklen_t as uint32_t in order to
align with Linux. Four bytes is enough for socket address length anyway.
