unix.7: Fix description of "pathname" sockets
As reported by Lennart Poettering:
The part about "pathname" sockets suggests usage of
sizeof(sa_family_t) + strlen(sun_path) + 1
for calculating the sockaddr size. Due to alignment/padding
this is probably not a good idea. Instead, one should use
offsetof(struct sockaddr_un, sun_path) + strlen() + 1
or something like that.
