Integrate tools/regression/acltools into the FreeBSD test suite as tests/sys/acl

- Make the requirements more complete for the testcases
- Detect prerequisites so the tests won't fail (zfs.ko is loaded, zpool(1)
is available, ACL support is enabled with UFS, etc).
- Work with temporary files/directories/mountpoints that work with atf/kyua
- Limit the testcases to work on temporary filesystems to reduce tainting the
test host

Integrate more tests into the FreeBSD test suite from tools/regression, etc

One more fix. Now all ACL tests pass again.

Make ACL tests slightly easier to run.

Recognize NFSv4 ACL semantics and run proper regression test.

Add regression test for NFSv4 ACLs on UFS.
