perf tools: Pass the struct opt to the wildcard parsing routine 

It is needed because it will call parse_event for each tracepoint
name that matches, and we pass the perf_evlist via opt->value.

Problem introduced in 4503fdd where my assumption about opt being
always non NULL made me not look at callers of parse_events outside
builtin-*.c.
