unix: use a type equivalent to reflect.SliceHeader to manipulate slices

The regression test included in this change verifies that the type is,
in fact, equivalent, while allowing the actual header definitions to
avoid importing the (relatively heavy) "reflect" package itself.

This change is loosely based on Keyan Pishdadian's draft in CL 230557.

For golang/go#37805
