Capture/Replay: Limit number of compile processes based on load

When replaying, for each batch a limited number of compile processes is launched, but no all-over limit is set, so that on computers with a low processor count and/or limited working memory the machine may become un-responsive. Therefore, tell ninja to not spawn new processes when the load is larger than the number of available processors.
