tests: make running ls in a no longer existing directory more portable

On Linux, ls -A simply returns nothing and the exit code is 0.
On NetBSD, ls -A complains that . doesn't exist and the exit code is 1.

Sadly, it's not possible to do something like "[1] (?)", so " || true" is the
best I could come up with.
