    libc/resolv: Switch default to loopback address

    If no resolver configuration was found, we would fall back to INADDR_ANY
    and IN6ADDR_ANY.  This made sense when it was first written thirty or
    forty years ago but not today, especially since connecting to INADDR_ANY
    or IN6ADDR_ANY is no longer supported.  Switch to the loopback address
    and simplify the code.

    Note that (as the pre-existing comment in the code states) running
    without a resolver configuration is not really supported.  Still, if
    we're going to have a hardcoded fallback, it might as well work.
