Require that MAC label buffers be able to store a non-empty string.

The buffer size may be used to initialize an sbuf in
MAC_POLICY_EXTERNALIZE, and without this constraint it's possible to
trigger an assertion failure in the sbuf code.  With INVARIANTS
disabled, the first attempt to write to the sbuf will fail.
