Subject: iotests: Do not needlessly filter _make_test_img

In most cases, _make_test_img does not need a _filter_imgfmt on top.  It
does that by itself.

(The exception is when IMGFMT has been overwritten but TEST_IMG has not.
In such cases, we do need a _filter_imgfmt on top to filter the test's
original IMGFMT from TEST_IMG.)
