In v4l2-tracer-gen.pl, add support for setting the output directory for
the generated files and choosing which ones to generate (common, trace or
retrace). The default is to generate them all in the current directory,
i.e. what the script used to do.

[Append a '/' automatically between $outdir and $fname]
