    tools/ocaml/xenstored/store.ml: fix build error
    
    Building with Dune in release mode fails with:
    ```
    File "ocaml/xenstored/store.ml", line 464, characters 13-32:
    Warning 18: this type-based record disambiguation is not principal.
    File "ocaml/xenstored/store.ml", line 1:
    Error: Some fatal warnings were triggered (1 occurrences)
    ```
    
    This is a warning to help keep the code futureproof, quoting from its
    documentation:
    > Check information path during type-checking, to make sure that all types 
are
    > derived in a principal way. When using labelled arguments and/or 
polymorphic
    > methods, this flag is required to ensure future versions of the compiler 
will
    > be able to infer types correctly, even if internal algorithms change. All
    > programs accepted in -principal mode are also accepted in the default 
mode with
    > equivalent types, but different binary signatures, and this may slow down 
type
    > checking; yet it is a good idea to use it once before publishing source 
code.
