Make sure that the termid type is initialized to AU_IPv4 by default.

This makes sure that process tokens credentials with un-initialized
audit contexts are handled correctly.  Currently, when invariants are
enabled, this change fixes a panic by ensuring that we have a valid
termid family.  Also, this fixes token generation for process tokens
making sure that userspace is always getting a valid token.

This is consistent with what Solaris does when an audit context is
un-initialized.
