RFR: 8301214: Adjust handshakeTimeout value in test HandshakeTimeout.java after 8189338

[Daniel Jeliński]

Please review this patch that reduces the socket timeout used in HandshakeTimeout test to its minimum value of 1 millisecond.

This change makes the test complete 10 seconds faster; before this change it took 5 seconds for the handshake to timeout, and the test attempts 2 handshakes.

The change also makes the test more likely to pass when it has to compete with other tests for CPU time.
