Break level system.transfer.list for android 5.x and 6.x

The new tool generates errors for older versions.

For example, Android 5.1 had to be level 2 instead has been compiled as a level 4 as attached files.

Confirmed.

As img2sdat binary cannot determine which system you are trying to compress, I have to add the ability to choose the correct one, as a workaround.
