Subject: [PATCH] tests: Add pathological iso9660 filesystem tests

These are not added to grub-fs-tester because they are not generated and
none of the filesystem tests are run on these ISOs. The test is to run the
command "ls /" on the ISO, and a failure is determined if the command
times out, has non-zero return value or has any output.
