the rpm arch will be the output of uname -m

As i've said previously I personally prefer arm64 I think it will be
better for users but they will learn if it ends up being aarch64.


if uname -m is arm64 we will have foo-1.1-1.arm64.rpm 
if uname -m ends up as aarch64 we will have foo-1.1-1.aarch64.rpm
