restore sapling getdeps so eden/mononoke can depend on it

Summary:
X-link: facebookincubator/zstrong#994

Bring a manifest for sapling back so we can test eden fs and mononoke. Their tests need the hg binary and thus a sapling manifest to depend upon

How:
 * started with backout of 73302ef03f2d10e45a36aaa2354b4f722cd71e07 and badf6d159dada727acfb5394bd17de223b336975
