build: add missing bits for material-examples package

[jelbourn]

Adds:

• Missing flatModuleId from the ngc options
• Missing typing for module in order to set moduleId
• Makes templateUrl and styleUrls for example components match material
  components.

Is this module.id available in plunkers?

[devversion]

The moduleId should be removed by the inline resources script. Why do we need it at all?

[jelbourn]

It was part of my debugging process. It ended up not being the problem, but I left it because the material2 components themselves use it. However, I didn't think of the plunkers. It looks like I failed to update how those work at all. Fixing that now...

[devversion]

I see. Basically they shouldn't be necessary at all. It's fine to leave them for now though.

Just want to check. Does something need the moduleId in our development? (e.g Google internally)

[jelbourn]

Yes- Google uses it

[devversion]

Alright that makes sense then. For the examples you removed the module.id. You can remove the typings file therefore too

[jelbourn]

Updated to remove moduleId for examples

[devversion]

LGTM. One minor comment about the unused typing file.
