Remove explicit SSLSocket.startHandshake

When dalvik-dev merges to master, startHandshake will imply that the
caller wants a fully synchronous handshake instead of using handshake
cutthrough. This removes an unnecessary startHandshake so that
handshake cutthrough won't be disabled for Apache http connections.

    This change brings Abstract verify into sync with the code from
    javax.net.ssl.DefaultHostnameVerifier from dalvik-dev which also
    removed this same duplicated code.
