init: change --manifest-depth default to 1v2.60.2

Most users do not care about the manifest history in .repo/manifests/.
Let's change the default to 1 so things work smoothly for most people
most of the time.  For the rare folks who want the full history, they
can add --manifest-depth=0 to their `repo init`.

This has no effect on existing checkouts.

Spot checking Android & CrOS manifests shows significant speedups.
Full history can take O(10's seconds) to O(minutes) while depth of 1
takes constant time of O(~5 seconds).
