[PATCH v1 4/8] iotests: filter out compression_type

[Denis Plotnikov <dplotnikov@virtuozzo.com>]

After adding compression type feature to qcow2 format, qemu framework
commands reporting the image settingd, e.g. "qemu-img create", started
reporting the compression type for the image which breaks the iotests
output matching.

To fix it, add compression_type=zlib to the list of filtered image parameters.
