Don't include Component-format Ruby in npm packages

The Component-format Ruby is not yet ready for JS-host environments, and
is decoupled by `jco transpile` during the build process. Thus, users
generally don't need the Component-format binary, and just use the
transpiled version.
Removing the binary reduces the package size and it fits within jsdelivr
size limits.
