perf symbols: Generalize filter in __fprintf_buildid methods

Browse Source 
We had that 'with_hits' filter to show just the build ids for DSOs that
had samples, make that generic so that we can use it in the upcoming
buildid-cache --missing feature, to show just the build ids that are not
in the cache.
