init: add --manifest-upstream-branch

When a sha1 is provided to '--manifest-branch', the ref which
is expected to contain that sha1 can be provided using the new
'--manifest-upstream-branch' option. This is useful with
'--current-branch' to avoid having to sync all heads and tags,
or with a commit that comes from a non-head/tag ref (like a
Gerrit change ref).
