syz-manager: use 3 VMs per bug reproduction
As the process is single-threaded, the positive contribution of each
additional VM allocated for the repro generation process decreases.
For GCE VMs (mostly used by syzbot), the time to set up a VM instance
is usually less than 5 minutes. The time to run a single test that
doesn't crash the VM is ~ 10 minutes and actually most runs will be like
that.
Therefore we have plenty of time to set up a VM while another one is being
tested (on average).
Let's save resources and use 3 VMs instead of 4: one for running the
test, one is prepared in parallel and one speeds up processing in the case
of transient errors and for cases when a reproducer is able to crash a
VM quickly.
