Title: Max load average

Add -l N option to limit the load average.

This is similar to GNU make -l/--load-average option. It limits the number of job started if the load average exceed the given value. It can be very useful when running ninja on a continuous integration server where we want to use parallelism as much as possible without overloading the server.
