init: use --current-branch by default

People rarely care about having all manifest branches locally.  Change
the default to only pull down the selected branch.  If people want other
branches, the -b option will fetch it automatically, or people can use
--no-current-branch.

This only applies to the manifest project syncing, not the rest of the
projects that are in the checkout.
