[PATCH] perf symbol: Print symbol offsets conditionally

[PATCH] perf symbol: Print symbol offsets conditionally

[Namhyung Kim]

The __symbol__fprintf_symname_offs() always shows symbol offsets.  So
there's no difference between 'perf script -F ip,sym' and 'perf script
-F ip,sym,symoff'.  I don't think it's a desired behavior..
