Subject: remove last use of sin_len from gotwebd

This removes the last use of sin_len from gotwebd to avoid using
it in the -portable code base.

gotwebd still works for me with both unix sockets and tcp sockets.

I don't think this assignment to sin_len is needed at all, because
sin_len is already being set via got_sockaddr_inet[6]_init() during
the configuration stage.

ok?
