Now that we've got a firmware that can do TFTP booting on s390x (i.e.
the pc-bios/s390-netboot.img), we can enable the PXE tester for this
architecture, too.

Since this only adds a test, I guess this could still be included
for 2.10 ... otherwise, I think it's also OK to simply postpone this
to 2.11 instead
