update the build to dora 1.0 and a shell-free build command

dora 1.0 runs a node's build command directly rather than through a shell, so
the mkdir/cd/&& sequence in dataflow.yml could not work. Move it to
scripts/build.sh and invoke that instead.

Default CMAKE_BUILD_TYPE to Release so DoraTargets.cmake picks the release
cargo profile and the binary does not link debug dora bindings.

Pin the dataflow source with tag: — 1.0 replaced git_checkout with the
mutually exclusive tag/rev/branch.
