leaking_addresses: Always print a trailing newline
For files that lack trailing newlines and match a leaking address (e.g. wchan[1]), the leaking_addresses.pl report would run together with the next line, making things look corrupted. Unconditionally remove the newline on input, and write it back out on output.
