gnu: commencement: Use system in %final-inputs.

Otherwise this causes odd issues, I presume arising from when %current-system
differs from the system argument passed to %final-inputs.

* gnu/packages/commencement.scm (%final-inputs): Set %current-system to
system.
* gnu/packages/base.scm (%final-inputs): Add optional system parameter.
* gnu/ci.scm (base-packages): New procedure to memoize the base packages
depending on system.
(package->job): Pass system to base-packages.
