git,remote: use universal new lines for fetch/pull stderr capture

See gitpython-developers#1969

stderr parser call RemoteProgress update on each line received.
With universal_newlines set to False, there is a mixup between
line feed and carriage return.
In the `handle_process_output` thread, this is thus seen as a single
line for the whole output on each steps.
