This wasn't set before (in this case). Doing so breaks many qcow2+file
tests (28, to be exact), because they rely on being able to do something
like

TEST_IMG="${TEST_IMG}.base" _make_test_img

which fails now because _make_test_img resorts to TEST_IMG_FILE.

I guess the fix would be for them to use TEST_IMG_FILE in those places
instead of TEST_IMG; but it's not always so simple. For instance, test
017 sets TEST_IMG and then relies on the io() function provided by
common.pattern to use that image, so maybe 017 would need to set both
TEST_IMG and TEST_IMG_FILE.
