build: Use pkg-config to find FreeType
pkg-config is apparently preferred over freetype-config these days (see the BUGS section of freetype-config(1)). pkg-config support was added to FreeType in version 2.1.5, which was released in 2003, so it should comfortably be available everywhere by now. We no longer need to explicitly substitute FREETYPE_CFLAGS and FREETYPE_LIBS, since PKG_CHECK_MODULES does that automatically. Fixes Debian bug #887721.
