perf symbols: Store if there is a filter in place
When setting yup the symbols library we setup several filter lists, for dsos, comms, symbols, etc, and there is code that, if there are filters, do certain operations, like recalculate the number of non filtered histogram entries in the top/report TUI. But they were considering just the "Zoom" filters, when they need to take into account as well the above mentioned filters (perf top --comms, --dsos, etc). So store in symbol_conf.has_filter true if any of those filters is in place.
