perf tools: Fix build failure on 32-bit arch
Failed in 32bit arch build like this:
CC /opt/h00206996/output/perf/arm32/builtin-record.o
util/session.c: In function ‘perf_session__warn_about_errors’:
util/session.c:1304:9: error: format ‘%lu’ expects argument of type ‘long unsigned int’,
but argument 2 has type ‘long long unsigned int’ [-Werror=format=]
builtin-report.c: In function ‘perf_evlist__tty_browse_hists’:
builtin-report.c:323:2: error: format ‘%lu’ expects argument of type ‘long unsigned int’,
but argument 3 has type ‘u64’ [-Werror=format=]
Replace %lu format strings in warning message with PRIu64 for u64
'total_lost_samples' to fix this problem.
