perf tools: Fix handling of wildcards in tracepoint event selectors
It wasn't accounting the ':' when consuming bytes in the the event
selector string, so parse_events() would fail in this test:
if (!(*str == 0 || *str == ',' || isspace(*str)))
return -1;
as *str would be pointing to '*', the last character in the '-e' arg in:
