Have grit survive a Windows registry with Unicode keys.

Have grit survive a Windows registry with Unicode keys.

grit triggered a python bug http://bugs.python.org/issue9291 that
broke the build. This change is to rely only on the internal
python mime type list which contains everything we need anyway.

Looks like another repository that cq doesn't manage.

pastarmovj and thakis, are you able to help with the legwork please?

[Nico, 2014-04-24 17:50:15]

I'll land this.

The only two repos where the cq works are chrome (both src/ and tools/) and
blink.
