perf hists browser: Inform how to reset the symbol filter
When in the hists browser, i.e. in 'perf report' or in 'perf top', it is
possible to press '/' and specify a substring to filter by symbol name.
Clarify how to remove a filter by making the prompt be:
Please enter the name of symbol you want to see.
To remove the filter later, press / + ENTER
