Currently a call that both accepts and creates a resource
self-justifies itself and thus is always enabled.
A good example is accept call. Accepts are always self-enable
and thus enable all other syscalls that work with the socket.
Calculate TransitivelyEnabledCalls in the opposite direction
to resolve this. Start with empty set of enable syscalls,
then enable syscalls that don't accept any resources,
then enable syscalls that accept resources created by the
previous batch of syscalls, and so on.
This prevents self-enablement of accept.
