Subject: [PATCH 2/3] Makefile: add prereq check for the Open Sans font.

The fc-list command from media-libs/fontconfig can tell us what fonts
are available to rsvg-convert, so this commit asks it if any font
matching the pattern "Open Sans" is installed. You could make this
check a bit more bullet-proof by checking the exact string (to avoid
matching e.g. Not Open Sans), but only at the expense of making a
simple command more complicated.
