testbot/VMs: Make sure $VM->Errors does not overflow.

The Errors field definition only allows two digits which sounds like
more than enough for a count of consecutive errors but can overflow in a
few days if the VM hosts are knocked out, which then causes the scripts
to die.
It would be easy to increase the maximum number of digits but that would
only postpone the issue so add VM::AddError() to make sure the field
does not overflow.
