Find binaries in alternate location
Find binaries in alternate location

When `bundle_path` is configured via `$HOME/.bundle/config`, for some reason Bundler creates the bundle using a slightly different directory structure. Rather than putting binaries in `$bundle_path/ruby/*/bin/`, Bundler puts them in `$bundle_path/bin/`. When making shims, also search for binaries in the latter path.
