perf trace/scripting: Add support for script args
One oversight of the original scripting_ops patch was a lack of
support for passing args to handler scripts. This adds
argc/argv to the start_script() scripting_op, and changes the
rw-by-file script to take 'comm' arg rather than the 'perf'
value currently hard-coded. It also takes the opportunity to do
some related minor cleanup.
