tests/boot-serial: Check the 40p machine, too

The "40p" machine is using the Open Hack'Ware BIOS, just like the "prep"
machine, so we can test it accordingly with the boot-serial tester, too.
While we're at it, also change the strings that we are using for the
"prep" machine, so that this test now also checks some CLI parameters.
