ninjatool: rebuild multi-output targets if outputs are missing
The "stamp file trick" used to group targets of a single multi-output rule prevents the user from deleting one such target in order to force its rebuild. Doing so will not touch the stamp file, and therefore only the dummy ":" command will be executed. With this patch, ninjatool writes rules that force-rebuild the stamp file if any of its outputs are missing. Rebuilding the missing target therefore causes the stamp file to be rebuilt too.
