perf tools: Simplify evsel__add_modifier()

Browse Source 
Since it doesn't set the exclude_guest, no need to special handle the
bit and simply show only if one of host or guest bit is set.  Now the
default event name might not have :H prefix anymore so change the
dlfilter test not to compare the ":" at the end.
