tests/qemu-iotest: Add more image formats to the thorough testing

Now that the "check" script is a little bit smarter with providing
a list of tests that are supported for an image format, we can also
add more image formats that can be used for generic block layer
testing. (Note: qcow1 and luks are not added because some tests
there currently fail, and other formats like bochs, cloop, dmg and
vvfat do not work with the generic tests and thus would only get
skipped if we'd tried to add them here)
