rv: Remove trailing whitespace from tracepoint string

Browse Source 
RV event tracepoints print a line with the format:
    "event_xyz: S0 x event -> S1 "
    "event_xyz: S1 x event -> S0 (final)"

While printing an event leading to a non-final state, the line
has a trailing white space (visible above before the closing ").

Adapt the format string not to print the trailing whitespace if we are
not printing "(final)".
