store: 'mapm/accumulate-builds' does not compare stores with 'eq?'.
Fixes <https://issues.guix.gnu.org/51732>.
Regression introduced in 2015d3f042870860efef10e801b93eacc0742d38.
The (eq? store expected-store) comparison doesn't work on this branch
where the functional cache, with 'cache-object-mapping', is used
extensively, thereby changing the store's object identity.
* guix/store.scm (build-accumulator): Compare the socket of STORE and
EXPECTED-STORE rather than the store themselves.
