    build/cups: remove checks for httpGetAuthString and http_t.authstring
    
    httpGetAuthString() was added with cups 1.3 and we depend on a newer version
    now. The direct field access was a fallback in case httpGetAuthString()
    was missing, so this can also be dropped.
    
    Ported to master from !938
