Use carriage returns for data insertion logs in pgbench on terminal 

This is similar to what pg_basebackup and pg_rewind do when reporting
cumulative data, and that's more user-friendly.  Carriage returns are
now used when stderr points to a terminal, and newlines are used in
other cases, like a redirection to a log file.
