[Qemu-block] [PATCH v2 for-4.0] tests/qemu-iotests/235: Allow fallback to tcg

[Thomas Huth]

iotest 235 currently only works with KVM - this is bad for systems where
it is not available, e.g. CI pipelines. The test also works when using
"tcg" as accelerator, so we can simply add that to the list of accelerators,
too.

 v2: Do not remove the test from the "quick" group, since there was no
     real consensus about that change. We should maybe introduce a "ci"
     group instead later where this test here won't get added (since it
     currently does not work with accel=qtest)
