Update the Path2D polyfill for Node.js environments

Browse source 
The polyfill that we use was recently split into two packages, and it now consists of a "core" package and a browser-specific package that build upon the former.
Hence we need to update to use the "core" package, and slightly tweak the code that loads/initializes the polyfill; see also https://www.npmjs.com/package/path2d

This patch was tested successfully with the [pdf2png example](https://github.com/mozilla/pdf.js/tree/master/examples/node/pdf2png), after running `gulp dist-install` locally, using [this PDF document](https://bug810214.bmoattachments.org/attachment.cgi?id=9254990) which contains Type3-fonts that render using `Path2D`.
