Speedup prebuilt binary (#1188)

After the merge of #1184, CI now takes 11m just to shallow clone
crates.io git index, which means that our user using alternative git
index would also be quite slow.

This commit speeds it up by building all dependencies with `-O3` in dev
and release build, in release build we build everything with `-O3`.
