net: sockets: change socketpair related buffer and heap size

Latest supplicant uses 1K buffer size for sending control message via
socketpair, so reducing the NET_SOCKETPAIR_BUFFER_SIZE to save memory
footprint. There are 4 socketpairs for supplicant only case, and 6
socketpairs for hostapd case, update the heap size correspondingly.
