Use new aarch64 fcos repos

Now that aarch64 fcos is an official thing, we no longer need to use the side repo (for lack of a better word).  We can now use the same image lookup technique as x86_64.  I removed the special lookup, moved the x86_64 lookup to generic arch, and removed the arch specific files that we no longer needed.

[NO TESTS NEEDED]
