Evas font-engine: Remove dependency or harfbuzz being built with glib.

Harfbuzz needs unicode querying functions in order to work properly,
until there'll be a nice lib that does that (should be under dev) we have
to depend on an outside source. This commit uses new Harfbuzz API that
lets us not care about the unicode function provider and just let harfbuzz
to manage it on it's own.
