Fix client simulations

Browse Source 
parse_tls_serverhello() checks $TLS_CLIENT_HELLO for a supported_versions extension, and if it contains one, checks that the negotiated version is listed in that extension. However, while $TLS_CLIENT_HELLO is always set in socksend_tls_clienthello() it is not set by client_simulation_sockets() (or any of the functions that client_simulation_sockets() calls). As a result, when the server's response to a client simulation is parsed, parse_tls_serverhello() may compare the negotiated version against the supported_versions extension from a ClientHello message from a previous test.

This PR fixes the problem by having client_simulation_sockets() set $TLS_CLIENT_HELLO.
