perf annotate: Remove requirement of passing a symbol name

If the user doesn't pass a symbol name to annotate, it will
annotate all the symbols that have hits, in order, just like
'perf report -s comm,dso,symbol'.

This is a natural followup patch to the one that uses
output_hists to find the symbols with hits.

The common case is to annotate the first few entries at the top
of a perf report, so lets type less characters.
