Add a test case to check if the converted fs has device extent beyond boundary. The disk layout of source ext4 fs needs some extents to make them allocated at the very end of the fs. The script is from the original reporter. Also, since the existing convert tests always uses 512M as device size, which is not suitable for this test case, make it to grab the existing device size to co-operate with this test case.
