Generate CDI specifications for architectures other than x86_64

[arnaldo2792]

The nvidia-ctk helper program fails to parse the ldcache file for aarch64 because the list of flags in the code that parses this file is incomplete, compared to its counterpart in libnvidia-container

I was able to fix this by updating this part of the code to use flagArchAarch64 with value 0x0a00, as libnvidia-container does.

@arnaldo2792 would you be able to open a PR with your changes?

Update: I have created #1046 which should address this. Please confirm.
