fontconfig and fontconfig-native: upgrade to the latest version 2.8.0
fontconfig-native requires fontconfig, so upgraded both recipes;
renamed the patch directory from fontconfig-2.6.0 to fontconfig-2.8.0;
slightly rebased fix-pkgconfig.patch;
added HOMEPAGE, BUGTRACKER, LICENSE and LIC_FILES_CHKSUM;
updated LICENSE from "BSD" to "MIT-style & MIT & Public Domain";
reset PR to "r0".
