Pull Request Overview

This PR adds support for properly handling the --plugin-opt=stats-file option in LLD's --reproduce functionality. The --reproduce feature creates a tarball containing all inputs needed to reproduce a link, along with a response file to re-run the command. For output file options, the reproduce feature strips directory paths since the archive doesn't contain empty directories.

• Added OPT_plugin_opt_stats_file to the list of output file options that have their directory paths stripped in the reproduce response file
