perf probe: Show filename which contains target function

Show filename which contains a target function with the function name on
"--lines" mode, because perf-probe just shows the first function even if
there are many same-name functions.

Originally adopted by Franck Bui-Huu's patch which shows file name
instead of function name. I've just modified it to show both of function
name and file name, because of completeness of output.

E.g.)
$ perf probe -L t_show
<t_show@/home/mhiramat/ksrc/linux-2.6-tip/kernel/trace/ftrace.c:0>
0 static int t_show(struct seq_file *m, void *v)
1 {
2 struct ftrace_iterator *iter = m->private;
...

$ perf probe -L t_show@trace/trace.c
<t_show@/home/mhiramat/ksrc/linux-2.6-tip/kernel/trace/trace.c:0>
0 static int t_show(struct seq_file *m, void *v)
1 {
struct tracer *t = v;
...
