tracing: Remove spurious default precision from show_event_trigger/filter formats

Browse Source 
Change 2d8b7f9bf8 ("tracing: Have show_event_trigger/filter format a bit more in columns")
added space padding to align the output.
However it used ("%*.s", len, "") which requests the default precision.
It doesn't matter here whether the userspace default (0) or kernel
default (no precision) is used, but the format should be "%*s".
