Ryan Ernst c07f46409c Fix single newline in logging output stream buffer (#52253)
The buffer in LoggingOutputStream skips flushing when only a newline
appears. However, if a windows newline appeared, the buffer length was
not reset. This commit resets the length so the \r does not appear in
the next logging message.
