tests: avoid FP from 'find -files0-from DIR' on certain platforms

Browse Source 
On most modern systems like GNU/Linux, read(2)-ing from a directory file
descriptor will fail with EISDIR, but it succeeds e.g. on GNU/Hurd and
AIX-7.1/AIX-7.2.

tests/find/files0-from.sh: Skip the test case excercising a directory
argument for the -files0-from option when the system allows reading
from a directory.
