(simple_expect): If the starts with "<<<", remove it, and don't expect a line
leader. This is useful for catching messages from lyskomd that are created by libraries that we have no control over, and that don't emit the expected line leader. (set_debug_calls): New proc, extracted from lyskomd_start and lyskomd_fail_start. Expect the new message that is emitted when the debug calls are disabled. (lyskomd_start): New optional argument: pre_lock_messages. Moved code to set_debug_calls(). (lyskomd_fail_start): Ditto.
