[PULL 6/9] tests/qtest: Improve endianness-test to work with missing machines and devices

[Thomas Huth <thuth@redhat.com>]

The users might have built QEMU with less machines or without the
i82378 superio device. Add some checks to the endianess-test so that
it is able to deal with such stripped down QEMU versions, too.
