[Web] Implement dummy IPWeb instead of IPUnix

Note: This commit ties the IPUnix to the UNIX_SOCKET_UNAVAILABLE define,
disabling it when set. It is maybe not semantically correct (getifaddrs)
is not part of the "socket" API, but it's reasonable to expect that a
platform not supporting Unix-style sockets, would also not support other
Unix network functions.
