Other information

The main reason the benchmarks broke / went weird, were because of ubuntu-latest changing from 20.04 to 22.04.
This PR fixes the interpretation of results. But doesn't address the performance regression in #5800.

• fix(bench): Include clone3 in thread count
  It's a newer syscall interface and gets counted seperately in strace results.

• fix(bench): Update totals line parsing
  The column offsets didn't match up when usecs/call is included in the totals.

• fix(bench): Enforce locale, avoiding parse errors
  On my local machine, it used an NL locale changing the strace numbers to use commas.
  Adding this env var avoids that problem.

This don't yet fix #5800

The ubuntu update also caused issues with the strace output being different.
These patches account for the new format, but don't address the performance slowdown.

Restoring the syscalls and thread count to expected range.
