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.
