Do not mark base image files as inefficient files even it was installed through any dep

[vkosuri]

Hi,

I use dive_0.9.2_linux_amd64.deb on Ubuntu 22, My container already had the Perl package and its modules.

One of my docker RUN commands installs Perl packages as dependencies due to this Perl marking as inefficient Files,

Could you please let me know how to overcome this?
