build_deps.cmd: prevent over-subscription of the cpu.

/maxcpucount:1 and /m are the same option with the latter
one using all cores available, leading to the situation
where msbuild would start N side by side project builds
that all tried to use N cores as well. leading to severe
memory and compute starvation during the deps build.
