socket: add define for socket name length
The function osmo_sock_get_name_buf() can be used to write a string
representation to a user provided memory. Unfortunately the proper
length for the user provided memory is not obvious. To make using
osmo_sock_get_name_buf() more practical, add a define constant that
defines the length of the required memory. Also use this define in
socket.c.
