Fixes the OS's DNS servers list being ignored on Windows since #60997. This patch landed in c-ares in February, but with no sign of an imminent release, it's probably worth cherry-picking this; the impact is fairly significant.

Fixes: #62347

Original commit message:

    Fixes nodejs#1056

    The commit
    c-ares/c-ares@1d1b3d4
    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.
