"devkitA64_a7-x86_64-linux.tar.xz" still in image

Hi,

found a little issue while playing around with this image:

$ docker run -ti --rm greatwizard/devkita64
root@5727cb9a6570:/source# ls -lh /devkitA64_a7-x86_64-linux.tar.xz
-rw-r--r-- 1 root root 26M Mar 19 23:49 /devkitA64_a7-x86_64-linux.tar.xz

You are only deleting *.tar.bz2 in your dockerfile


Thanks for this great image anyways!
