base: Fix forcing loopback only binding for listeners.
Despite online documentation, the type used for sin_addr.s_addr is not
actually an unsigned long, it is an in_addr_t. When an unsigned long is a 64
bit value, the endian conversion moves the relevant bits of the 32 bit
in_addr_t to positions which are truncated away. This forces the value to 0
which means to bind to any interface, the opposite of the intended effect.
