    use nproc/2 workers for large ops job
    
    Commit 1ce19ab76d67a89b04f907f1d292d013a3b699e0 dropped API_WORKERS from
    nproc/2 to nproc/4 and also started using API_WORKERS for the number of
    conductor workers, so in gate runs that dropped conductor workers from 8
    to 2.  We're now seeing instance build timeouts in the large ops job.
    
    This change goes back to nproc/2 for the large ops job (VIRT_DRIVER=='fake').
