libpayload: i8042: Only test PS/2 AUX port when enabled
If a PS/2 AUX device is not present then the AUX test command during i8042_probe() will time out and add ~500ms to the boot time. In order to avoid this only test the PS/2 AUX port if CONFIG_LP_PC_MOUSE is enabled. BUG=b:126633269 TEST=boot on device without AUX port and check that this command does not get executed, saving ~500ms at boot.
