ci: Limit image and system tests jobs periodicity.

System tests and images jobs are extremely expensive in I/O operations and
storage size, pass a "period" argument to Cuirass to limit their periodicity.

* gnu/ci.scm (hours): New procedure,
(image-jobs, system-test-jobs, tarball-jobs): set a period argument.
