Subject: [PATCH] client.c: remove trailing newline from output for '-o -'

The CLI option '-o file' redirects the received payload into the
given file, where '-' denotes stdout. As the function close_output()
used to append a newline to the end of the output, certain tools
such as cbor2pretty.rb have failed, complaining about the trailing
character.

This change now writes the newline if only if option '-o' was not
specified.
