iprule: avoid trailing space in print_rule() after printing protocol

It seems print_rule() tries to avoid a trailing space at the end
of the line. At least, when printing details about the actions,
they no longer append the space. Probably expecting to be the
last attribute that will be printed.

Don't let the protocol add the trailing space. The space at the end
of the line should be printed consistently (or not).
