Subject: [PATCH] deps: c-ares: cherry-pick 8ba37af8e3fb

Original commit message:

    Fixes #1056

    The commit
    https://github.com/c-ares/c-ares/commit/1d1b3d4a808dff9359cacb4539ac1b775876dcb6
    refactored the function to use wide strings, but didn't touch this
    check. Because an empty wide string would now be size 2 and not 1, the
    empty string would go on and cause the DNS domain list to be replaced
    with nothing.
