Always load $ruby/dependencies.sh before $ruby/functions.sh.

* Merged the `load_dependencies` function into `init`, so that
  `$ruby_dependencies` is always set, even if the `--no-install-deps`
  option is given and the `install_deps` function is not called.
* CRuby's `configure_ruby` function requires that `$ruby_dependencies`
  be populated in order to check for the optional `gdbm` and `jemalloc`
  dependencies and add additional `./configure` options for them.
