Remove arch package

Remove the arch package from the utils module. The arch package
was only there to serve juju/juju directly. It dictated what was
supported in side of juju. The juju project should dictate what
architectures are supported, not a common utils package.

The arch package will be moved into juju/juju project, within the
core package.
