[PATCH v3 3/5] gitlab-ci: Introduce 'cross_accel_build_job' template

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Introduce a job template to cross-build accelerator specific
jobs (enable a specific accelerator, disabling the others).

The specific accelerator is selected by the $ACCEL environment
variable (default to KVM).

Extra options such disabling other accelerators are passed
via the $ACCEL_CONFIGURE_OPTS environment variable.
