scripts: Added -U/--undefine as inverse -D/--define to most scripts

Browse Source 
This adds -U/--undefine as an inverse -D/--define, allowing you to
select results where a given field does _not_ match a set of
values/globs.

For example, make bench-marks, which need to ignore stack/heap/usage
probes as a special case, can easily filter like so:

  $ ./scripts/csv.py test.csv -Uprobe=stack,heap,usage

---

One thing globbing is pretty bad at is inverse matches. This is
_usually_ easy enough to work around, but has been an annoyance enough
times that I think _some_ option to inverse filter is warranted.

I'm not sure -U/--undefine is the best name for this, since field isn't
really "undefined" as a result (well kinda? if you're relying on
implicit by/field rules?), but it gets the job done.
