builtin rebase: show progress when connected to a terminal

In this commit, we pass `--progress` to the `format-patch` command if stderr is connected to an interactive terminal, unless we're in quiet mode. This `--progress` option will be used in `format-patch` to show progress reports on stderr as patches are generated.
