bin-deps is resolved with other dependencies

[peter-jerry-ye]

Normally, the bin-deps should be resolved separately, since it is essentially locking a binary instead of a dependency tree. However, currently the bin-deps is resolved with other dependencies, causing unnecessary dependency conflict.

But to solve this problem involves larger scale of changes. Currently the bin-deps is pulled and stored under .mooncakes, and built together. We may need to find elsewhere to build it properly.

#1508 solves the first step : stopping making the bin-deps transitive, because the bin-deps is expected to be used locally. We might later refactor the bin-deps system following the golang's tool design.
