iotests: rewrite check into python

Just use classes introduced in previous three commits. Behavior
difference is described in these three commits.

Drop group file, as it becomes unused.

Drop common.env: now check is in python, and for tests we use same
python interpreter that runs the check itself. Use build environment
PYTHON in check-block instead, to keep "make check" use the same
python.

Checking for virtio-blk moved to iotests.py, as it actually iotests.py
dependency. Actually not all python iotests depend on it, so in future
it may be refactored to checked only when really needed.
