this commit removes the code that was changing argv values, and replaces
it with a new array. Which is absolutly fine, as the argv / argc values
are never accessed later on. Only the copies that have been passed to
efl_main or elm_main.
This resolves several issues:
1. the for loop is useless, every single array element that gets
initialized with it, is some offset from argv[0] this may also crash
when argv[i] - argv[opt_args] is bigger strlen argv[0].
2. The memcpy here is super dangerous, the dest array is not garanteed
to have the same size as argv[0], this only works if the client
application name is shorter than the name "exactness_recorder"
3. The memset here is absolutly wrong. There is again no garantee that
the array has the expected size behind that, this was constantly
overwriting the segment after the place where argv was stored, which
was lukely enough on fedora always the environs, which deleted the
couple first segments. (This was not causing any fuzz, since they
have been sudo related env vars on the docker image). However, on
arch this just crashed right away. On Ubuntu this overwrote DISPLAY,
which resulted in the unability to launch the app.
