Namely, awk's printf("%d") doing what it's supposed to do, cast
it's operand to (int), which screws up large numbers.
The fix is simple, although it mostly just pushes the problem
under the rug; using %.0f instead of %d.
- Redirect STDERR for the collection part in both tools
- rm_tempdir in sigtrap
- A part of pt-mysql-summary still depended on the system being run,
rather than the samples being read. Now it works properly.
