tests: Don't assume find continues after filesystem loops

POSIX says

> When it detects an infinite loop, find shall write a diagnostic
> message to standard error and shall either recover its position in the
> hierarchy or terminate.

So make the 'links' folder not have any loops, and add a new 'loops'
folder for testing the GNU/bfs behaviour.
