[PATCH v2 evemu 12/13] python: use the evemu lib to print the event description

[Peter Hutterer]

Instead of our manual printf format, use the library. That's a bit convoluted
since evemu_write_event expects a FILE*, so we need to create a temporary file
just for the str() function.

Changes to v1:
- new patch, didn't exist before

I did play around with fmemopen, cffi etc. but it's not really much simpler
and until someone complains about the performance, we can leave that here.
