* Add build deps to Xorg libraries

* Add build deps to Xorg utilities

* Add packages for Xorg fonts and font-related utilities

* Change font deptype from build to default

I wasn't sure which deptype was appropriate at first since none of
the packages are actually linked together. I initially chose the
build deptype for this reason. However, the font packages don't
install into their own prefix. They install into font-config. If
font-config is a build dependency, that means you can uninstall it
without uninstalling the font packages, which wouldn't make sense
since they install into font-config. So I switched them back to
the default deptype.
