clone: use a real progress meter for connectivity check
Because the initial connectivity check for a cloned
repository can be slow,
0781aa4 (clone: let the user know
when check_everything_connected is run, 2013-05-03) added a
"fake" progress meter; we simply say "Checking connectivity"
when it starts, and "done" at the end, with nothing between.
Since check_connected() now knows how to do a real progress
meter, we can drop our fake one and use that one instead.
