Fix liboverride extreme resync times in case of libraries dependency loops.

That max number of `10000` level of recursivity was a typo (should have
been `1000`), but even that is way too high, typical sane situation
should not lead to more than a few tens of levels, so reducing the max
level to 200.

Also improve error message with more context info about the issue.

Found while investigating issues for the Blender Studio's Heist production.
