WI: set identity to client secret if missing (#15121)
Allocations created before 1.4.0 will not have a workload identity token. When
the client running these allocs is upgraded to 1.4.x, the identity hook will run
and replace the node secret ID token used previously with an empty string. This
causes service discovery queries to fail.

Fallback to the node's secret ID when the allocation doesn't have a signed
identity. Note that pre-1.4.0 allocations won't have templates that read
Variables, so there's no threat that this new node ID secret will be able to
read data that the allocation shouldn't have access to.
