Bundlex: error creating symlink when priv directory exists

[gBillal]

Bundlex creates symbolic links for the plugins to the precompiled libraries. However the link is pointing to non-existing folder if the project has a priv directory. Elixir uses symlink for the priv directory inside _build which leads to errors like this

** (File.LinkError) could not create symlink from "../../../../bundlex/priv/shared/precompiled/httpsgithub.comBtbNFFmpeg-Buildsreleasesdownloadlatestffmpeg-n6.1-latest-linux64-gpl-shared-6.1.tar.xz/lib" to "/home/xxxxx/p/OpenSourceProjects/elixir/membrane/membrane_h264_ffmpeg_plugin/_build/dev/lib/membrane_h264_ffmpeg_plugin/priv/bundlex/nif/httpsgithub.comBtbNFFmpeg-Buildsreleasesdownloadlatestffmpeg-n6.1-latest-linux64-gpl-shared-6.1.tar.xz": file already exists

Hello @gBillal! I think release v1.4.6 should solve this problem.

After this fix, there's no issue on building a project with priv folder, however when creating a release there's an error when trying to copy the content of the wrong symlink generated by bundlex since Elixir doesn't seem to copy the content of the symlink but where the symlink points
