emacs-build-system: Fix 'package-name-version->elpa-name-version'.

Fixes a regression introduced in b7c7c03eb5e37fc3455e4e17b0898ffc4bca29c3.

* guix/build/emacs-build-system.scm (package-name-version->elpa-name-version):
  Remove unused 'name' binding.  Do not abuse 'strip-store-file-name' to
  remove the "emacs-" prefix, which worked before b7c7c03eb5 but not after.
