perf tools: Pass build_id object to build_id__sprintf()
Passing build_id object to build_id__sprintf function, so it can operate with the proper size of build id. This will create proper md5 build id readable names, like following: a50e350e97c43b4708d09bcd85ebfff7 instead of: a50e350e97c43b4708d09bcd85ebfff700000000 Signed-off-by: Jiri Olsa <jolsa@kernel.org> Acked-by: Ian Rogers <irogers@google.com> Link: https://lore.kernel.org/r/20201013192441.1299447-5-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
