Some tests have strict requirements on the filesystem permissions for certain files and directories. This adds a regress/check-perm tool that copies the relevant logic from sshd to exactly test the paths in question. This lets us skip tests when the local filesystem doesn't conform to our expectations rather than continuing and failing the test run. ok dtucker@
