Ludovic Courtès ac19950507 gnu: bootstrap: Cache the 'bootstrap-executable' origins. ...

This reduces the number of lookups in the 'add-data-to-store' cache from
2705 to 2685 (hit rate: 10% to 9%) when running:

  GUIX_PROFILING=add-data-to-store-cache guix build libreoffice -nd

* gnu/packages/bootstrap.scm (raw-build)[->store]: Use 'lower-object'
instead of 'origin->derivation'.  This allows the origin-to-derivation
mapping to be cached.
