Make white labeling even easier (#240)

Creating a white labeled build of the riff cli is now possible:

    NAME=ostinato make build

Produces a binary at `./bin/ostinato`

The path within the project for built binaries has moved to `./bin/riff`
and for packaged artifacts to `./dist/riff-linux-amd64.tgz`. The bin and
dist directories are ignored from git.
