Set make max load when building libtorch (#89237)
The nccl build is still OOM sometimes when using `$(MAKE)`:
```
virtual memory exhausted: Cannot allocate memory
Makefile:73: recipe for target '/var/lib/jenkins/cpp-build/caffe2/build/nccl/obj/collectives/device/devlink.o' failed
make[5]: *** [/var/lib/jenkins/cpp-build/caffe2/build/nccl/obj/collectives/device/devlink.o] Error 1
make[5]: Leaving directory '/var/lib/jenkins/workspace/third_party/nccl/nccl/src/collectives/device'
```

So trying to set the same limit here as when building with ninja
