takora: only move artifacts when $BRANCH is defined

The purpose of this change is to make the build script work with both
the "takora" job and the "takora-pull-requests" job.

In the takora-pull-requests job, $BRANCH is undefined. We don't need to
move the build artifacts, because we aren't going to save them.
