Cleanup stix_fonts_demo example.

anntzer · anntzer · commit 64ee57416c2a · 2018-07-04T18:09:35.000+02:00
- The `s` variable conditionally defined was never used. - The `'--latex' in sys.argv` branch (which dates back to the origin of the example, a567601), likely never worked (\mathbb requires \usepackage{amsfonts}), so just kill it. - Saving the figure doesn't really help with the example and tends to clutter the source tree when running the example, so don't do it.
