qemu-iotests: Correct 026 output

Because l2_allocate now frees the unused L2 cluster on error, the

tests: allow qemu-iotests to be run against nbd backend

To do this, we start a qemu-nbd process at _make_test_img and kill
it in _cleanup_test_img. $TEST_IMG is changed to point at the TCP
server. We also remove the checks for existence of binaries from
common.config - they're duplicated in common, and we can make the...
