vtls: fix potential ssl_buffer stack overflow
In Curl_multissl_version() it was possible to overflow the passed in
buffer if the generated version string exceeded the size of the buffer.
Fix by inverting the logic, and also make sure to not exceed the local
buffer during the string generation.
Closes #3863
