Subject: [PATCH] ci/eval: remove ofborg references

By now, these files have been changed enough to not need the "vendored
from" notes anymore. These links would still be there when going through
the history of the file, but today GHA CI has not many similarities
anymore to what ofborg did, so these are not really helpful.

(cherry picked from commit 2aae1425298dc478f02c9f05c01762b656975fd2)
