[OE-core] [Patch 0/1] pixbufcache.bbclass: gdk-pixbuf-query-loaders depends on libz

[Konrad Scherer]

Another native sstate minor issue. Reuse of native sstate file for
gdk-pixbuf-native fails in the pixbufcache_sstate_postinst. The file
gdk-pixbuf-query-loaders attempts to use the host libz. Adding the
dependency to zlib-native ensures the sstate for zlib-native is
available.
