update.sh: do not ignore git failures

git describe is expected to fail when HEAD is not exactly at a tag.
However, the set +e used for this check also allowed fetch, checkout,
and pull failures to be ignored, causing less useful missing-file errors
later in the script.

Re-enable set -e immediately after recording the git describe result so
that subsequent Git operations fail at the actual error.
