project-lakitu: sys-process/audit: apply the initial COS modification

When sys-process/audit was first created in COS by commit f56a9bfa5b75
("add audit tools in sys-process/audit") in
src/private-overlays/overlay-lakitu-private repository, its ebuild
file was different from the upstream Gentoo's ebuild file.

This commit applies those differences to the new ebuild file for
version 2.8.5 .
