gdk-pixbuf: Add 2.22.1 as new recipe

Updating gtk+ to 2.23.2 requires gdk-pixbuf, which is originaly a module in gtk+.
Borrow hardcoded_libtool.patch from original gtk+, and add configure_fix.patch
to fix build failure in cross-compile environment.

As gdk-pixbuf is a stand-alone package now, gdk-pixbuf-csource-native can be
safely removed. So extend gdk-pixbuf with native support, and make related
packages depend on it.
