[PULL 18/18] iotests: don't test qcow2.py inside 291

[Max Reitz <mreitz@redhat.com>]

From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>

820c6bee534ec3b added testing of qcow2.py into 291, and it breaks 291
with external data file. Actually, 291 is bad place for qcow2.py
testing, better add a separate test.

For now, drop qcow2.py testing from 291 to fix the regression.
