Fixed handling of unix sockets in $binary_remote_addr.

Previously, unix sockets were treated as AF_INET ones, and this may
result in buffer overread on Linux, where unbound unix sockets have
2-byte addresses.

Note that it is not correct to use just sun_path as a binary representation
for unix sockets.  This will result in an empty string for unbound unix
sockets, and thus behaviour of limit_req and limit_conn will change when
switching from $remote_addr to $binary_remote_addr.  As such, normal text
representation is used.
