test1148: tolerate progress updates better (again)

- Ignore intermediate progress updates.

- Support locales that use a character other than period as decimal
  separator (eg 100,0%).

test1148 checks that the progress finishes at 100% and has the right
bar width. Prior to this change the test assumed that the only progress
reported for such a quick transfer was 100%, however in rare instances
(like in the CI where transfer time can slow considerably) there may be
intermediate updates. For example, below is stderrlog1148 from a failed
CI run with explicit \r and \n added (it is one line; broken up so that
it's easier to understand).

\r
\r##################################                                        48.3%
\r######################################################################## 100.0%
\n
