[v3,1/4] v4l2-tracer: autogenerate files that can be added to git

Message ID 864bad34a41467f9d669ff3d422842ab47f52ed1.1701450544.git.deborah.brouwer@collabora.com

A comment at the beginning of the autogenerated files provides an absolute
path to the location of the autogeneration script. In preparation for
adding these files to the git repository, remove this absolute path.

Also, the autogeneration script was adding an extra newline to
trace-gen.cpp which was causing a whitespace warning, so remove that
too.
