    vtls: replaced getenv() with curl_getenv()
    
    Fixed undefined symbol of getenv() which does not exist when compiling
    for Windows 10 App (CURL_WINDOWS_APP). Replaced getenv() with
    curl_getenv() which is aware of getenv() absence when CURL_WINDOWS_APP
    is defined.
    
    Closes #2171
