Use ppa:mongodb-arm64/ppa by default when running on arm64/trusty
We know that the version of mongodb that shipped in trusty is insufficient for arm64, so there's no point in having the charm try to use it. Instead, default to pulling from a Canonical-maintained PPA - but still respect a user's "source" config setting if specified.
