This is the second attempt to fix our Git history. This should allow
"git blame" to work correctly in the upb/ directory even though our
automation unexpectedly blew away that directory.
In order to flip the flag, all downstream projects should be adapted.
However, it is hard to fix them all if there are constant regressions.
Adding it to the CI will ensure that once the project can build with
incompatible_disallow_empty_glob it can keep building like that.
