iotests: Fix a problem in common.filter

If TEST_DIR is set to /tmp, test case 144 will fail. The reason is that
TEST_DIR resembles 144's test image name tmp.qcow2.
When 144 is testing $TEST_DIR/tmp.qcow2, it wants to replace
$TEST_DIR/tmp.qcow2 to TEST_DIR/tmp.qcow2, but actually it will fail
and get TEST_DIRTEST_DIR.qcow2 in this case.
The fix is just to modify the code to replace $TEST_DIR/ with TEST_DIR/.
