[OE-core] [PATCH] buildhistory: remove duplicate renames

[Anuj Mittal]

In cases when a package like qemu might have files with same names
in multiple directories, the rename logic might go wrong and create
multiple rename pair for a single directory.

Make sure that we process each rename pair once. Also, don't print
FILELIST as part of PKGSIZE to ensure that it gets printed only once
when reporting package changes.

Fixes [YOCTO #12559]
