perf/scripts: Add syscall tracing scripts

Adds a set of scripts that aggregate system call totals and system
call errors.  Most are Python scripts that also test basic
functionality of the new Python engine, but there's also one Perl
script added for comparison and for reference in some new
Documentation contained in a later patch.
