tests/fd: Error out early if more fds are open

Browse Source 
This is simply an error in test setup. There's a limit to how far we
can isolate them from the system.

(it's possible new cmake versions close fds automatically since I
can't reproduce the original issue via `ninja test` or `make test`)

Fixes #9017
