Older kernels (e.g., RHEL6) do system call tracing via the
syscalls:sys_{enter,exit} tracepoints rather than using raw_syscalls:*.
Update perf python and perl scripts to fallback to syscalls:* when
raw_syscalls:* isn't available.

A couple small fixes for the failed syscalls script:
- The script description says it can be restricted to a specific comm,
make it so.
- silence the match output in the shell script

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.
