Test fixes: Since fix for CONC-603 (wrong error handling in TLS read/write) in case of a read/write error client doesn't return always error 2013 (server has gone away), so in addition we need to check for error 2026 (TLS/SSL error) and 5014 (write error).

# Killing a connection in an embedded server does not work like in a normal
|
|
# server, if it is waiting for a new statement. In an embedded server, the
|
|
# connection does not read() from a socket, but returns control to the
|
|
# application. 'mysqltest' does not handle the kill request.
