Hi,

After some tries, our babel 7.9.6 has the same behavior than `npm i`
downloaded one. So I prepared a workaround:
 * use debian/nodejs/extcopies (with a little change in pkg-js-tools to
   avoid an error with babel 7.4.5 ; => pkg-js-tools_0.9.37)
 * add a little patch to be compatible with babel 7.9.6 error messages

I'm ready to upload both node-rollup-plugin-babel and pkg-js-tools,
waiting for eventual comments (all is pushed to salsa)
