tst_QSslSocket::qtbug18498_peek() - fix several problems 

It all started from the compiler's warnings about 'this' captured but
not used in lambdas. While fixing this it was noticed that 'client' socket
has a lifetime longer than the test case itself (the socket has a parent,
which is tst_QSslSocket object). The 'server' socket was simply leaked.
So there is no guarantee that some of them (or both) later, after the
test failed in one of QVERIFY, for example, does not emit 'encrypted'
upon receiving more data; this will result: in reading/writing from/to
invalid memory location (captured local 'encryptedCount') and/or probably
exiting event loop when it's not expected to do so.
