[PATCH v4 04/14] rv: Remove trailing whitespace from tracepoint string
From: Gabriele Monaco <gmonaco@redhat.com>

Subsystem:
runtime verification (rv), the rest, tracing · Maintainers:

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)".
