Subject: [PATCH v2 3/8] scripts/leaking_addresses: remove command line options
Currently script accepts files to skip. This was added to make running
the script faster (for repeat runs). We can remove this functionality in
preparation for adding sub commands (scan and format) to the script.
Remove command line options.
