acl: new tests

[Bruno Haible]

Hi Jim,

Now I've got support for ACL for these platforms:
  Linux, FreeBSD, MacOS X, Tru64, IRIX (POSIX like API),
  Solaris, probably also Cygwin (Solaris API),
  HP-UX,
  AIX.

For the start, I added the unit tests. It will certainly break on some platforms
temporarily, but this is harmless since you have already released 
coreutils-6.12.
