CI "Run require test" is broken

[Aire-One]

Recent PRs are green, but the "codecov-lua5.3" logs are not good:

Run cd "/home/runner/work/awesome/awesome/build" && make check-requires
+ cd /home/runner/work/awesome/awesome/build
+ make check-requires
Checking use of require()
depgraph not found

(this error is non-fatal; we just skip its use)
Built target check-requires

1. This should be a fatal error
2. It needs to be fixed
