Make amber-phone images possible right now

amber-phone-staging has about everything now but amber-phone
is still waiting for transitions. So in order to be able to
have images with a correct source.list bootstrap with
amber-phone-staging and switch back to amber-phone afterwards.

This can be removed in about a week when packages transitioned,
we can also drop 0037c22d then.
