[bug#64874] [PATCH] guix: tuned-package: Use target on cross-compile.

[Jean-Pierre De Jesus DIAZ via Guix-patches via <guix-patches@gnu.org>]

* guix/transformations.scm (tuned-package): Use either bag-target if
  available or bag-system to select the CPU architecture of the package
  that is going to be tuned.  This enables the tuning of cross-compiled
  packages.
