add fontcache.bbclass

All font packages should inherit this class in order to generate the
proper postinst/postrm scriptlets.

The scriptlets will actually create a host intercept hook that will be
executed at the end, at do_rootfs time, after all packages have been
installed. This is good when there are many font packages.
