ls: Remove trailing whitespace so that tests pass
When in modes `-C` and `-x` we need to remove the trailing whitespace on each line. This is the behavior of other `ls` commands. Other `ls` commands will print the last filename and then print a newline. Prior to this patch we would print the last filename, followed by two spaces, and then print a newline. Previously, we would get to the end of the loop and print the padding. I couldn't figure out a way to determine when the program had reached the end of a line. So I piggybacked off of the newline code.
