for proc tables the actual services supported is known only after the
handshake.  However, we still assume K_ANY for them, and it's a bit
gross.  This is a step toward respecting what the actual table reported
it supports.

(this is also needed for Gilles' diff to offload authentication, since
otherwise all proc tables will hit the K_AUTH codepath.)

We could also remove K_ANY and leave the default services for the table
proc to zero at this point.

ok?
