plugin: use original .bin for native modules

Uses the original project's .bin folder when building native modules.
Cordova prepare step resolves the symbolic links instead of preserving
them, which causes fails when building modules that depend on linked
modules, such as node-pre-gyp. With this change, the native modules
build step will try to use the original project's linked binaries.
