Variants Code in custompios doesn't match make_custom_pi_os

[jxmx]

If I execute the following:

./src/make_custom_pi_os -v raspios_lite_arm64 -g ./asl3
cd asl3/src
sudo ./build_dist

Then make_custom_pi_os downloads the latest Raspbian lite image to a directory named image. However
when custompios is called out of build_dist it is looking for the file in a directory named image-raspberrypiarm64.
The script fails. Manual mv image image-raspberrypiarm64 and rerunning build_dist fixes the issue.
