perf tools: Allow to reset open files counter
I hit a bug when running test suite without forking each test (-F option): $ perf test -F dso 8: Test dso data read : Ok 9: Test dso data cache : FAILED! 10: Test dso data reopen : FAILED! The reason the session file limit is set just once for perf process so we need to reset it for each test, otherwise wrong limit is taken into account.
