Update font list for the SDK

Java has a problem loading OpenType fonts. This change updates the list
of fonts to include by omitting the otf fonts and adding their
replacement.

This change also moves the code for configuring the fonts for the SDK in
a separate file so that the core Makefile remains cleaner.
