Subject: iotests.py: implement unsupported_imgopts

Git-commit: 7c15400cdd06b7b9b26c86eac1858fb9c0d77c1c

We are going to support some addition IMGOPTS in python iotests like
in bash iotests. Similarly to bash iotests, we want a way to skip some
tests which can't work with specific IMGOPTS.

Globally for python iotests we will not support things like
'data_file=$TEST_IMG.ext_data_file' in IMGOPTS, so, forbid this
globally in iotests.py.
