Call to `git lfs pull` should be allowed to fail

[petefoth]

Running a build with the pf-build-iodeOS branch, one of the repos did not allow calls to git lfs pull and responded wth a 405 error. This caused the whole script to fail, and the build run to abort

This call should be allowed to fail without crashing / exiting the build

docker-lineage-cicd/src/new_build.sh

Line 289 in 6c80034

repo forall -v -c git lfs pull &>> "$repo_log"

Solution is to call set +eu before the call, and set -eu after it

It will be an issue in the master branch too. I will try to fix this in the pf-build-iodeOS branch for now, so that my Iode builds can succeed

This is fixed in `pf-build-iodeOS branch.

I'll leave this open until it gets into master branch also
