actions: use access() as an initial validity check in contained_followlink() if access() returns error then the symlink cannot be dereferenced for some reason, and it is pointless walking the symlink because it will fail. This also deals with cases where a symbolic link is circular, generating -ELOOP, and so we don't have to worry about dealing with loops ourselves.
