delete-old status under /usr/ (amd64 context example)

I created a /tmp/main-amd64-installed-from-scratch/ and installed into it
with:

installworld distrib-dirs distribution DB_FROM_SRC=1 installkernel

in a boot context with:

# uname -apKU
FreeBSD amd64-ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT amd64 1400093 #106 main-n264334-215bab7924f6-dirty: Tue Jul 25 18:49:51 PDT 2023     root@amd64-ZFS:/usr/obj/BUILDs/main-amd64-nodbg-clang/usr/main-src/amd64.amd64/sys/GENERIC-NODBG amd64 amd64 1400093 1400093

I use delete-old and delete-old-libs with -DBATCH_DELETE_OLD_FILES
in my update procedures and have for years. delete-old use is a
step in scripts, not a manual operation. (delete-old-libs use
requires more timing control and so is less automatic.)

I find the following when I look for potential old files in /usr/ compared
to what ended up in /tmp/main-amd64-installed-from-scratch/usr/ . Much of
the output seems to be old files that are still around but likely should
not be.
