Previously, passing `-v` would emit an overwhelming amount of logging:

This info is occasionally useful when debugging bootstrap itself, but not very useful for figuring
out why a config option was ignored or command wasn't run.  Demote it to `-vv` logging so that `-v`
is more useful.
This already enables `download-rustc`, so it's quick to build rustdoc,
and this makes it less confusing when changes to rustdoc aren't reflected in the docs.

Note that this uses 2 and not 1 because `download-rustc` only affects stage 2 runs.
